Cloudflare incident on October 30, 2023

Multiple Cloudflare services were unavailable for 37 minutes on October 30, 2023. This was due to the misconfiguration of a deployment tool used by Workers KV. This was a frustrating incident, made more difficult by Cloudflare’s reliance on our own suite of products. We are deeply sorry for the impact it had on customers. What follows is a discussion of what went wrong, how the incident was resolved, and the work we are undertaking to ensure it does not happen again.

Workers KV is our globally distributed key-value store. It is used by both customers and Cloudflare teams alike to manage configuration data, routing lookups, static asset bundles, authentication tokens, and other data that needs low-latency access.

During this incident, KV returned what it believed was a valid HTTP 401 (Unauthorized) status code instead of the requested key-value pair(s) due to a bug in a new deployment tool used by KV.

These errors manifested differently for each product depending on how KV is used by each service, with their impact detailed below.

What was impacted

A number of Cloudflare services depend on Workers KV for distributing configuration, routing information, static asset serving, and authentication state globally. These services instead received Continue reading

AMD’s Instinct GPU Business Is Coiled To Spring

Timing is a funny thing. The summer of 2006 when AMD bought GPU maker ATI Technologies for $5.6 billion and took on both Intel in CPUs and Nvidia in GPUs was the same summer when researchers first started figuring out how to offload single-precision floating point math operations from CPUs to Nvidia GPUs to try to accelerate HPC simulation and modeling workloads. …

Worth Reading: Taming the BGP Reconfiguration Transients

Almost exactly a decade ago I wrote about a paper describing how IBGP migrations can cause forwarding loops and how one could reorder BGP reconfiguration steps to avoid them.

One of the paper’s authors was Laurent Vanbever who moved to ETH Zurich in the meantime where his group keeps producing great work, including the Chameleon tool (code on GitHub) that can tame transient loops while reconfiguring BGP. Definitely something worth looking at if you’re running a large BGP network.

Cisco and Aviz coordinate support for enterprise SONiC networks

Cisco is teaming with Aviz Networks to offer an enterprise-grade SONiC offering for large customers interested in deploying the open-source network operating system.Under the partnership, Cisco’s 8000 series routers will be available with Aviz Networks’ SONiC management software and 24/7 support. The support aspect of the agreement may be the most significant portion of the partnership, as both companies attempt to assuage customers’ anxiety about supporting an open-source NOS.While SONiC (Software for Open Networking in the Cloud) is starting to attract the attention of some large enterprises, deployments today are still mainly seen in the largest hyperscalers. With this announcement, Cisco and Aviz are making SONiC more viable for smaller cloud providers, service providers, and those very large enterprises that own and operate their own data centers, said Kevin Wollenweber, senior vice president and general manager with Cisco networking, data center and provider connectivity.To read this article in full, please click here

Introducing notifications for HTTP Traffic Anomalies

When it comes to managing Internet properties, the difference between a small technical hiccup and major incident is often a matter of speed. Proactive alerting plays a crucial role, which is why we were excited when we released HTTP Error Rate notifications — giving administrators visibility into when end users are experiencing errors.

But what if there are issues that don't show up as errors, like a sudden drop in traffic, or a spike?

Today, we're excited to announce Traffic Anomalies notifications, available to enterprise customers. These notifications trigger when Cloudflare detects unexpected changes in traffic, giving another valuable perspective into the health of your systems.

Unexpected changes in traffic could be indicative of many things. If you run an ecommerce site and see a spike in traffic that could be great news — maybe customers are flocking to your sale, or you just had an ad run on a popular TV show. However, it could also mean that something is going wrong: maybe someone accidentally turned off a firewall rule, and now you’re seeing more malicious traffic. Either way, you might want to know that something has changed.

Similarly, a sudden drop in traffic could mean many things. Perhaps Continue reading
