IBM Outlines Steps To Verify Claims Of Quantum Advantage

D-Wave executives stirred up some controversy earlier this year when they claimed a smaller version of its Advantage 2 annealing quantum system, armed with 1,200 qubits, had reached “quantum supremacy,” – or “quantum advantage” – that significant but ill-defined time when a quantum system is able to solve a problem in much less time, at a lower cost, or more efficiently than the most powerful classical supercomputer. …

Reducing double spend latency from 40 ms to < 1 ms on privacy proxy

One of Cloudflare’s big focus areas is making the Internet faster for end users. Part of the way we do that is by looking at the "big rocks" or bottlenecks that might be slowing things down — particularly processes on the critical path. When we recently turned our attention to our privacy proxy product, we found a big opportunity for improvement.

What is our privacy proxy product? These proxies let users browse the web without exposing their personal information to the websites they’re visiting. Cloudflare runs infrastructure for privacy proxies like Apple’s Private Relay and Microsoft’s Edge Secure Network.

Like any secure infrastructure, we make sure that users authenticate to these privacy proxies before we open up a connection to the website they’re visiting. In order to do this in a privacy-preserving way (so that Cloudflare collects the least possible information about end-users) we use an open Internet standard – Privacy Pass – to issue tokens that authenticate to our proxy service.

Every time a user visits a website via our Privacy Proxy, we check the validity of the Privacy Pass token which is included in the Proxy-Authorization header in their request. Before we cryptographically validate a user's token, we check Continue reading

Perplexity is using stealth, undeclared crawlers to evade website no-crawl directives

We are observing stealth crawling behavior from Perplexity, an AI-powered answer engine. Although Perplexity initially crawls from their declared user agent, when they are presented with a network block, they appear to obscure their crawling identity in an attempt to circumvent the website’s preferences. We see continued evidence that Perplexity is repeatedly modifying their user agent and changing their source ASNs to hide their crawling activity, as well as ignoring — or sometimes failing to even fetch — robots.txt files.

The Internet as we have known it for the past three decades is rapidly changing, but one thing remains constant: it is built on trust. There are clear preferences that crawlers should be transparent, serve a clear purpose, perform a specific activity, and, most importantly, follow website directives and preferences. Based on Perplexity’s observed behavior, which is incompatible with those preferences, we have de-listed them as a verified bot and added heuristics to our managed rules that block this stealth crawling.

How we tested

We received complaints from customers who had both disallowed Perplexity crawling activity in their robots.txt files and also created WAF rules to specifically block both of Perplexity’s declared crawlers: PerplexityBot and Perplexity-User. Continue reading

Vulnerability disclosure on SSL for SaaS v1 (Managed CNAME)

Earlier this year, a group of external researchers identified and reported a vulnerability in Cloudflare’s SSL for SaaS v1 (Managed CNAME) product offering through Cloudflare’s bug bounty program. We officially deprecated SSL for SaaS v1 in 2021; however, some customers received extensions for extenuating circumstances that prevented them from migrating to SSL for SaaS v2 (Cloudflare for SaaS). We have continually worked with the remaining customers to migrate them onto Cloudflare for SaaS over the past four years and have successfully migrated the vast majority of these customers. For most of our customers, there is no action required; for the very small number of SaaS v1 customers, we will be actively working to help migrate you to SSL for SaaS v2 (Cloudflare for SaaS).

Background on SSL for SaaS v1 at Cloudflare

Back in 2017, Cloudflare announced SSL for SaaS, a product that allows SaaS providers to extend the benefits of Cloudflare security and performance to their end customers. Using a “Managed CNAME” configuration, providers could bring their customer’s domain onto Cloudflare. In the first version of SSL for SaaS (v1), the traffic for Custom Hostnames is proxied to the origin based on the IP addresses assigned to the Continue reading

For Financial Services Firms, AI Inference Is As Challenging As Training

A decade ago, when traditional machine learning techniques were first being commercialized, training was incredibly hard and expensive, but because models were relatively small, inference – running new data through a model to cause an application to act or react – was easy. …

Top 5 Kubernetes Network Issues You Can Catch Early with Calico Whisker

Kubernetes networking is deceptively simple on the surface, until it breaks, silently leaks data, or opens the door to a full-cluster compromise. As modern workloads become more distributed and ephemeral, traditional logging and metrics just can’t keep up with the complexity of cloud-native traffic flows.

That’s where Calico Whisker comes in. Whisker is a lightweight Kubernetes-native observability tool created by Tigera. It offers deep insights into real-time traffic flow patterns, without requiring you to deploy heavyweight service meshes or packet sniffer. And here’s something you won’t get anywhere else: Whisker is data plane-agnostic. Whether you run Calico eBPF data plane, nftables, or iptables, you’ll get the same high-fidelity flow logs with consistent fields, format, and visibility. You don’t have to change your data plane, Whisker fits right in and shows you the truth, everywhere.

Let’s walk through 5 network issues Whisker helps you catch early, before they turn into outages or security incidents.

1. Policy Misconfigurations

Traditional observability tools often show whether a packet was forwarded, accepted or dropped, but not why. They lack visibility into which Kubernetes network policy was responsible or if one was even applied.

With Whisker, each network flow is paired with:

Mythbusting IPv6: Why Adoption Lags and What Will Change It

IPv6 was developed in the late 1990s as a successor to IPv4 to address the internet’s rapid growth and prevent IPv4 address exhaustion. The original vision was that, after a period of dual-stack operation, IPv4 would be phased out. Over 25 years later, full-scale depletion of IPv4 addresses is imminent, yet IPv6 adoption remains slow — currently only about 30% worldwide, with the same proportion of Alexa Top 1,000 websites reachable via IPv6. The timeline for a full transition remains uncertain. Understanding IP Addresses: The Internet’s Postal System Before diving into the complexities of IPv6 adoption, it’s essential to understand what these protocols actually do. Think of IP addresses as the internet’s equivalent of postal addresses — they tell data packets where to go across the vast network of interconnected computers that make up the internet. IPv4 vs. IPv6 address space: A scale comparison The scale difference is staggering.
