Cloudflare insights in the tools you're already using
Data analytics is a frequent theme in conversations with Cloudflare customers. Our customers want to understand how Cloudflare speeds up their websites and saves them bandwidth, ranks their fastest and slowest pages, and be alerted if they are under attack. While providing insights is a core tenet of Cloudflare's offering, the data analytics market has matured and many of our customers have started using third-party providers to analyze data—including Cloudflare logs and metrics. By aggregating data from multiple applications, infrastructure, and cloud platforms in one dedicated analytics platform, customers can create a single pane of glass and benefit from better end-to-end visibility over their entire stack.
While these analytics Continue reading

Verizon 和某 BGP 优化器如何在今日大范围重创互联网
大规模路由泄漏影响包括 Cloudflare 在内的主要互联网服务
事件经过
在 UTC 时间今天（ 2019年6月24号）10 点 30 分，互联网遭受了一场不小的冲击。通过主要互联网转接服务提供供应商 Verizon (AS701) 转接的许多互联网路由，都被先导至宾夕法尼亚北部的一家小型公司。这相当于 滴滴错误地将整条高速公路导航至某小巷 – 导致大部分互联网用户无法访问 Cloudflare 上的许多网站和许多其他供应商的服务。这本不应该发生，因为 Verizon 不应将这些路径转送到互联网的其余部分。要理解事件发生原因，请继续阅读。
此类不幸事件并不罕见，我们以前曾发布相关博文。这一次，全世界都再次见证了它所带来的严重损害。而Noction “BGP 优化器”产品的涉及，则让今天的事件进一步恶化。这个产品有一个功能：可将接收到的 IP 前缀拆分为更小的组成部分（称为更具体前缀）。例如，我们自己的 IPv4 路由 104.20.0.0/20 被转换为 104.20.0.0/21 和 104.20.8.0/21。就好像通往 ”北京”的路标被两个路标取代，一个是 ”北京东”，另一个是 ”北京西”。通过将这些主要 IP 块拆分为更小的部分，网络可引导其内部的流量，但这种拆分原本不允许向全球互联网广播。正是这方面的原因导致了今天的网络中断。
为了解释后续发生的事情，我们先快速回顾一下互联网基础“地图”的工作原理。“Internet”的字面意思是网络互联，它由叫做自治系统（AS）的网络组成，每个网络都有唯一的标识符，即 AS 编号。所有这些网络都使用边界网关协议（BGP）来进行互连。BGP 将这些网络连接在一起，并构建互联网“地图”，使通信得以一个地方（例如，您的 ISP）传播到地球另一端的热门网站。
通过 BGP，各大网络可以交换路由信息：如何从您所在的地址访问它们。这些路由可能很具体，类似于在 GPS 上查找特定城市，也可能非常宽泛，就如同让 GPS 指向某个省。这就是今天的问题所在。
宾夕法尼亚州的互联网服务供应商（AS33154 - DQE Communications）在其网络中使用了 BGP 优化器，这意味着其网络中有很多更具体的路由。具体路由优先于更一般的路由（类似于在滴滴 中，前往北京火车站的路线比前往北京的路线更具体)。
DQE 向其客户（AS396531 - Allegheny）公布了这些具体路由。然后，所有这些路由信息被转送到他们的另一个转接服务供应商 (AS701 - Verizon)，后者则将这些"更好"的路线泄露给整个互联网。由于这些路由更精细、更具体，因此被误认为是“更好”的路由。
泄漏本应止于 Verizon。然而，Verizon 违背了以下所述的众多最佳做法，因缺乏过滤机制而导致此次泄露变成重大事件，影响到众多互联网服务，如亚马逊、Linode 和 Cloudflare。
这意味着，Verizon、Allegheny 和 DQE 突然之间必须应对大量试图通过其网络访问这些服务的互联网用户。由于这些网络没有适当的设备来应对流量的急剧增长，导致服务中断。即便他们有足够的能力来应对流量剧增，DQE、Allegheny 和 Verizon 也不应该被允许宣称他们拥有访问 Cloudflare、亚马逊、Linode 等服务的最佳路由...
在事件中，我们观察到，在最严重的时段，我们损失了大约 15% 的全球流量。
如何防止此类泄漏？
有多种方法可以避免此类泄漏：
一，在配置 BGP 会话的时候，可以对其接收的路由网段的数量设置硬性限制。这意味着，如果接收到的路由网段数超过阈值，路由器可以决定关闭会话。如果 Verizon 有这样的前缀限制，这次事件就不会发生。设置前缀数量限制是最佳做法。像 Verizon 这样的供应商可以无需付出任何成本便可以设置。没有任何合理的理由可以解释为什么他们没有设置这种限制的原因，只能归咎为草率或懒惰可能就是因为草率或懒惰。
二，网络运营商防止类似泄漏的另外一种方法是：实施基于 IRR （Internet Routing Registry）的筛选。IRR 是因特网路由注册表，各网络所有者可以将自己的网段条目添加到这些分布式数据库中。然后，其他网络运营商可以使用这些 IRR 记录，在与同类运营商产生BGP 会话时，生成特定的前缀列表。如果使用了 IRR 过滤，所涉及的任何网络都不会接受更具体的网段前缀。非常令人震惊的是，尽管 IRR 过滤已经存在了 24 年（并且有详细记录），Verizon 没有在其与 Allegheny的 BGP 会话中实施任何此类过滤。IRR 过滤不会增加 Verizon 的任何成本或限制其服务。再次，我们唯一能想到的原因是草率或懒惰。
三，我们去年在全球实施和部署的 RPKI 框架旨在防止此类泄漏。它支持对源网络和网段大小进行过滤。Cloudflare 发布的网段最长不超过 20 位。然后，RPKI 会指示无论路径是什么，都不应接受任何更具体网段前缀。要使此机制发挥作用，网络需要启用 BGP 源验证。AT&T 等许多供应商已在其网络中成功启用此功能。
如果 Verizon 使用了 RPKI，他们就会发现播发的路由无效，路由器就能自动丢弃这些路由。
Cloudflare 建议所有网络运营商立即部署 RPKI！
上述所有建议经充分浓缩后已纳入 MANRS（共同协议路由安全规范）
事件解决
Cloudflare 的网络团队联系了涉事网络：AS33154 (DQE Communications) 和 AS701 (Verizon)。联系过程并不顺畅，这可能是由于路由泄露发生在美国东海岸凌晨时间。
我们的一位网络工程师迅速联系了 DQE Communications，稍有耽搁之后，他们帮助我们与解决该问题的相关人员取得了联系。DQE 与我们通过电话合作，停止向 Allegheny 播发这些“优化”路线路由。我们对他们的帮助表示感谢。采取此措施后，互联网变回稳定，事态恢复正常。
很遗憾，我们尝试通过电子邮件和电话联系 Verizon，但直到撰写本文时（事件发生后超过 8 小时），尚未收到他们的回复，我们也不清楚他们是否正在采取行动以解决问题。
Cloudflare 希望此类事件永不发生，但很遗憾，当前的互联网环境在预防防止此类事件方面作出的努力甚微。现在，业界都应该通过 RPKI 等系统部署更好，更安全的路由的时候。我们希望主要供应商能效仿 Cloudflare、亚马逊和 AT&T，开始验证路由。尤其并且，我们正密切关注 Verizon 并仍在等候其回复。
尽管导致此次服务中断的事件并非我们所能控制，但我们仍对此感到抱歉。我们的团队非常关注我们的服务，在发现此问题几分钟后，即已安排美国、英国、澳大利亚和新加坡的工程师上线解决问题。
How Verizon and a BGP Optimizer Knocked Large Parts of the Internet Offline Today
Massive route leak impacts major parts of the Internet, including Cloudflare
What happened?
Today at 10:30UTC, the Internet had a small heart attack. A small company in Northern Pennsylvania became a preferred path of many Internet routes through Verizon (AS701), a major Internet transit provider. This was the equivalent of Waze routing an entire freeway down a neighborhood street — resulting in many websites on Cloudflare, and many other providers, to be unavailable from large parts of the Internet. This should never have happened because Verizon should never have forwarded those routes to the rest of the Internet. To understand why, read on.
We have blogged about these unfortunate events in the past, as they are not uncommon. This time, the damage was seen worldwide. What exacerbated the problem today was the involvement of a “BGP Optimizer” product from Noction. This product has a feature that splits up received IP prefixes into smaller, contributing parts (called more-specifics). For example, our own IPv4 route 104.20.0.0/20 was turned into 104.20.0.0/21 and 104.20.8.0/21. It’s as if the road sign directing traffic to “Pennsylvania” was replaced by two road signs, one for “Pittsburgh, PA” and Continue reading

Comment Verizon et un optimiseur BGP ont affecté de nombreuses partie d’Internet aujourd’hu
Une fuite massive de routes a eu un impact sur de nombreuses parties d'Internet, y compris sur Cloudflare
Que s'est-il passé ?
Aujourd'hui à 10h30 UTC, Internet a connu une sorte de mini crise cardiaque. Une petite entreprise du nord de la Pennsylvanie est devenue le chemin privilégié de nombreuses routes Internet à cause de Verizon (AS701), un important fournisseur de transit Internet. C’est un peu comme si Waze venait à diriger le trafic d’une autoroute complète vers une petite rue de quartier : de nombreux sites Web sur Cloudflare et beaucoup d’autres fournisseurs étaient indisponibles depuis une grande partie du réseau. Cet incident n'aurait jamais dû arriver, car Verizon n'aurait jamais dû transmettre ces itinéraires au reste d’Internet. Pour en comprendre les raisons, lisez la suite de cet article.
Nous avons déjà écrit un certain nombre d’articles par le passé sur ces événements malheureux qui sont plus fréquents qu’on ne le pense.

Introducing time.cloudflare.com
This is a guest post by Aanchal Malhotra, a Graduate Research Assistant at Boston University and former Cloudflare intern on the Cryptography team.
Cloudflare has always been a leader in deploying secure versions of insecure Internet protocols and making them available for free for anyone to use. In 2014, we launched one of the world’s first free, secure HTTPS service (Universal SSL) to go along with our existing free HTTP plan. When we launched the 1.1.1.1 DNS resolver, we also supported the new secure versions of DNS (DNS over HTTPS and DNS over TLS). Today, we are doing the same thing for the Network Time Protocol (NTP), the dominant protocol for obtaining time over the Internet.
This announcement is personal for me. I've spent the last four years identifying and fixing vulnerabilities in time protocols. Today I’m proud to help introduce a service that would have made my life from 2015 through 2019 a whole lot harder: time.cloudflare.com, a free time service that supports both NTP and the emerging Network Time Security (NTS) protocol for securing NTP. Now, anyone can get time securely from all our datacenters in Continue reading

The Quantum Menace
Over the last few decades, the word ‘quantum’ has become increasingly popular. It is common to find articles, reports, and many people interested in quantum mechanics and the new capabilities and improvements it brings to the scientific community. This topic not only concerns physics, since the development of quantum mechanics impacts on several other fields such as chemistry, economics, artificial intelligence, operations research, and undoubtedly, cryptography.
This post begins a trio of blogs describing the impact of quantum computing on cryptography, and how to use stronger algorithms resistant to the power of quantum computing.
- This post introduces quantum computing and describes the main aspects of this new computing model and its devastating impact on security standards; it summarizes some approaches to securing information using quantum-resistant algorithms.
- Due to the relevance of this matter, we present our experiments on a large-scale deployment of quantum-resistant algorithms.
- Our third post introduces CIRCL, open-source Go library featuring optimized implementations of quantum-resistant algorithms and elliptic curve-based primitives.
All of this is part of Cloudflare’s Crypto Week 2019, now fasten your seatbelt and get ready to make a quantum leap.

Towards Post-Quantum Cryptography in TLS
We live in a completely connected society. A society connected by a variety of devices: laptops, mobile phones, wearables, self-driving or self-flying things. We have standards for a common language that allows these devices to communicate with each other. This is critical for wide-scale deployment – especially in cryptography where the smallest detail has great importance.
One of the most important standards-setting organizations is the National Institute of Standards and Technology (NIST), which is hugely influential in determining which standardized cryptographic systems see worldwide adoption. At the end of 2016, NIST announced it would hold a multi-year open project with the goal of standardizing new post-quantum (PQ) cryptographic algorithms secure against both quantum and classical computers.
Many of our devices have very different requirements and capabilities, so it may not be possible to select a “one-size-fits-all” algorithm during the process. NIST mathematician, Dustin Moody, indicated that institute will likely select more than one algorithm:
“There are several systems in use that could be broken by a quantum computer - public-key encryption and digital signatures, to take two examples - and we will need different solutions for each of those systems.”
Initially, NIST selected 82 candidates for further consideration from Continue reading

Introducing CIRCL: An Advanced Cryptographic Library
As part of Crypto Week 2019, today we are proud to release the source code of a cryptographic library we’ve been working on: a collection of cryptographic primitives written in Go, called CIRCL. This library includes a set of packages that target cryptographic algorithms for post-quantum (PQ), elliptic curve cryptography, and hash functions for prime groups. Our hope is that it’s useful for a broad audience. Get ready to discover how we made CIRCL unique.
Cryptography in Go
We use Go a lot at Cloudflare. It offers a good balance between ease of use and performance; the learning curve is very light, and after a short time, any programmer can get good at writing fast, lightweight backend services. And thanks to the possibility of implementing performance critical parts in Go assembly, we can try to ‘squeeze the machine’ and get every bit of performance.
Cloudflare’s cryptography team designs and maintains security-critical projects. It's not a secret that security is hard. That's why, we are introducing the Cloudflare Interoperable Reusable Cryptographic Library - CIRCL. There are multiple goals behind CIRCL. First, we want to concentrate our efforts to implement cryptographic primitives in a single place. This makes it easier Continue reading

Cloudflare’s Ethereum Gateway
Today, we are excited to announce Cloudflare's Ethereum Gateway, where you can interact with the Ethereum network without installing any additional software on your computer.
This is another tool in Cloudflare’s Distributed Web Gateway tool set. Currently, Cloudflare lets you host content on the InterPlanetary File System (IPFS) and access it through your own custom domain. Similarly, the new Ethereum Gateway allows access to the Ethereum network, which you can provision through your custom hostname.
This setup makes it possible to add interactive elements to sites powered by Ethereum smart contracts, a decentralized computing platform. And, in conjunction with the IPFS gateway, this allows hosting websites and resources in a decentralized manner, and has the extra bonus of the added speed, security, and reliability provided by the Cloudflare edge network. You can access our Ethereum gateway directly at https://cloudflare-eth.com.
This brief primer on how Ethereum and smart contracts work has examples of the many possibilities of using the Cloudflare Distributed Web Gateway.
Primer on Ethereum
You may have heard of Ethereum as a cryptocurrency. What you may not know is that Ethereum is so much more. Ethereum is a distributed virtual computing network that stores and enforces smart Continue reading
