If you are wondering why Intel chief executive officer Pat Gelsinger has been working so hard to get the company’s foundry business not only back on track but utterly transformed into a merchant foundry that, by 2030 or so can take away some business from archrival Taiwan Semiconductor Manufacturing Co, the reason is simple. …

Data exfiltration and ransomware attacks in cloud-native applications are evolving cyber threats that pose significant risks to organizations, leading to substantial financial losses, reputational damage, and operational disruptions. As Kubernetes adoption grows for running containerized applications, it becomes imperative to address the unique security challenges it presents. This article explores the economic impact of data exfiltration and ransomware attacks, their modus operandi in Kubernetes environments, and effective strategies to secure egress traffic. We will delve into the implementation of DNS policies and networksets, their role in simplifying egress control enforcement, and the importance of monitoring and alerting for suspicious egress activity. By adopting these measures, organizations can strengthen their containerized application’s security posture running in Kubernetes and mitigate the risks associated with these prevalent cyber threats.
Data exfiltration and ransomware attacks have emerged as formidable threats to organizations worldwide, causing substantial financial losses and service outage. According to IBM’s 2023 Cost of a Data Breach report, data exfiltration attacks alone cost businesses an average of $3.86 million per incident, a staggering figure that underscores the severity of this issue. Ransomware attacks, on the other hand, can inflict even more damage, with Continue reading
We have said it before, and we will say it again right here: If you can make a matrix math engine that runs the PyTorch framework and the Llama large language model, both of which are open source and both of which come out of Meta Platforms and both of which will be widely adopted by enterprises, then you can sell that matrix math engine. …

A long-time friend sent me this question:
I would like your advice or a reference to a security framework I must consider when building a green field backbone in SR/MPLS.
Before going into the details, keep in mind that the core SR/MPLS functionality is not much different than the traditional MPLS:

There are events that unite people, like a total solar eclipse, reminding us, humans living on planet Earth, of our shared dependence on the sun. Excitement was obvious in Mexico, several US states, and Canada during the total solar eclipse that occurred on April 8, 2024. Dubbed the Great North American Eclipse, millions gathered outdoors to witness the Moon pass between Earth and the Sun, casting darkness over fortunate states. Amidst the typical gesture of putting the eclipse glasses on and taking them off, depending on if people were looking at the sky during the total eclipse, or before or after, what happened to Internet traffic?
Cloudflare’s data shows a clear impact on Internet traffic from Mexico to Canada, following the path of totality. The eclipse occurred between 15:42 UTC and 20:52 UTC, moving from south to north, as seen in this NASA image of the path and percentage of darkness of the eclipse.
Looking at the United States in aggregate terms, bytes delivered traffic dropped by 8%, and request traffic by 12% as compared to the previous week at 19:00 UTC Continue reading
We have been tracking the financial results for the big players in the datacenter that are public companies for three and a half decades, but starting last year we started dicing and slicing the numbers for the largest IT suppliers for stuff that goes into datacenters so we can give you a better sense what is and what is not happening out there. …

Here's a post we never thought we'd need to write: less than five months after one of our major data centers lost power, it happened again to the exact same data center. That sucks and, if you're thinking "why do they keep using this facility??," I don't blame you. We're thinking the same thing. But, here's the thing, while a lot may not have changed at the data center, a lot changed over those five months at Cloudflare. So, while five months ago a major data center going offline was really painful, this time it was much less so.
This is a little bit about how a high availability data center lost power for the second time in five months. But, more so, it's the story of how our team worked to ensure that even if one of our critical data centers lost power it wouldn't impact our customers.
On November 2, 2023, one of our critical facilities in the Portland, Oregon region lost power for an extended period of time. It happened because of a cascading series of faults that appears to have been caused by maintenance by the Continue reading

Developer Week 2024 has officially come to a close. Each day last week, we shipped new products and functionality geared towards giving developers the components they need to build full-stack applications on Cloudflare.
Even though Developer Week is now over, we are continuing to innovate with the over two million developers who build on our platform. Building a platform is only as exciting as seeing what developers build on it. Before we dive into a recap of the announcements, to send off the week, we wanted to share how a couple of companies are using Cloudflare to power their applications:
We have been using Workers for image delivery using R2 and have been able to maintain stable operations for a year after implementation. The speed of deployment and the flexibility of detailed configurations have greatly reduced the time and effort required for traditional server management. In particular, we have seen a noticeable cost savings and are deeply appreciative of the support we have received from Cloudflare Workers.

With VMware jacking up the prices and killing off the free version of ESXi, people are looking to alternatives for a virtualization platform. One of the more popular alternatives is Proxmox, which so far I’m really liking.
If you’re looking to run CVP on Proxmox, here is how I get it installed. I’m not sure if Proxmox counts as officially supported for production CVP (it is KVM, however), but it does work fine in lab. Contact Arista TAC if you’re wondering about Proxmox suitability.
Oddly enough, what you’ll want to do is get a copy of the CVP OVA, not the KVM image. I’m using the most recent release (at the time of writing, always check Arista.com) of cvp-2024.1.0.ova.
Get it onto your Proxmox box (or one of them if you’re doing a cluster). Place it somewhere where there’s enough space to unpack it. In my case, I have a volume called volume2, which is located at /mnt/pve/volume2.
I made a directory called tmp and copied the file to that directory via SCP (using FileZilla, though there’s several ways to get files onto Proxmox, it’s just a Linux box). I Continue reading
I’m preparing a blog post on setting up vPC in a VXLAN/EVPN environment. While doing so, I ran into some issues. Rather than simply fixing them, I wanted to share the troubleshooting experience as it can be useful to see all the things I did to troubleshoot, including commands, packet captures, etc., and learn a little about virtual networking. As always, thanks to Peter Palúch for providing assistance with the process.
The following topology implemented in ESX is used:
I had just configured the vPC peer link and vPC peer link keepalive. I verified that the vPC was functional with the following command:
Leaf1# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status : success
Per-vlan consistency status : success
Type-2 consistency status : success
vPC role : primary
Number of vPCs configured : 1
Peer Gateway : Disabled
Dual-active excluded VLANs : -

A few weeks ago I took a good look at the [Babel] protocol. I found a set of features there that I really appreciated. The first was a latency aware routing protocol - this is useful for mesh (wireless) networks but it is also a good fit for IPng’s usecase, notably because it makes use of carrier ethernet which, if any link in the underlying MPLS network fails, will automatically re-route but sometimes with much higher latency. In these cases, Babel can reconverge on its own to a topology that has the lowest end to end latency.
But a second really cool find, is that Babel can use IPv6 nexthops for IPv4 destinations - which is super useful because it will allow me to retire all of the IPv4 /31 point to point networks between my routers. AS8298 has about half of a /24 tied up in these otherwise pointless (pun intended) transit networks.
In the same week, my buddy Benoit asked a question about OSPFv3 on the Bird users mailinglist [ref] which may or may not have been because I had been messing around with Babel using only IPv4 loopback interfaces. And just a Continue reading
