It’s time to gather round the hedge and discuss whatever Eyvonne, Tom, and Russ find interesting! In this episode we discuss business logic vulnerabilities, and how we often forget to think outside the box to understand the attack surfaces that matter. We also discuss upcoming network speed increases like Wi-Fi 7 and 800G Ethernet. Do we really need these speeds, or are we just getting caught up in a hype cycle?
DHCPv6 Prefix Delegation (DHCPv6-PD) is an IETF RFC that lets a router delegate a long-lived prefix, using DHCP, to a requesting router. The hosts discuss how this is used today both by service providers and in the enterprise, and potential impacts on address allocation and planning.

The use of Event-Driven Ansible to enable fact gathering from events is considered a “Getting Started” type of use case, but it can be extremely powerful. This use case is simple and it is what we consider a “Read Only” type of action, meaning that we are not making any changes, but we are using the event to trigger a fact gathering process which we can later publish to the IT Service Management system.
The benefit with this is we are able to provide consistent automated troubleshooting and fact gathering which is used to enrich the ticketing systems, so when our engineers have a look at the incident, they have all the information they need to decide on the next steps to resolve the issue or situation. This can potentially save many hours of toil and ultimately save an organization money from reduced down time and faster resolutions. But, we are assuming that our technical teams will know what to do with this event data.
What if we could assist with filling the gap when an incident takes place, and we could receive information or even options on how to resolve the issues? This is where we could use Continue reading
Last time we built a network with two adjacent BGP routers. Now let’s see what happens when we add a core router between them:
As 2023 has progressed, the revenue growth projections at Arista Networks have inched up as its supply chain issues are getting resolved. …

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.
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
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. …
