DNS Problems Scaling With Kubernetes: Read More
DNS problems with Kubernetes, particularly intermittent delays, have been challenging moving our services to the Kubernetes platform for scaling.

The most severe Linux threat to surface in years catches the world flat-footed:
CopyFail threatens multi-tenant servers, CI/CD work flows, Kubernetes containers, and more.
Publicly released exploit code for an effectively unpatched vulnerability that gives root access to virtually all releases of Linux is setting off alarm bells as defenders scramble to ward off severe compromises inside data centers and on personal devices.

Despite the small team size,
Mastodon operates two large, production Mastodon instances:
mastodon.social
Runs on Kubernetes with autoscaling between 9 and 15 nodes (16 cores, 64 GB RAM each). Web frontend scale between 5 and 20 pods, while various Sidekiq worker pools scale between 10 and 40 pods. On average, mastodon.social has 70–80 pods running at any given time. This platform handles up to 300,000 active users per day and approximately 10 million requests per minute.

How Mastodon Runs OpenTelemetry Collectors in Production
At the beginning of 2025, the OpenTelemetry Developer Experience SIG published the results of its first community survey. One of the strongest themes was clear: teams want more real-world examples of how the OpenTelemetry SDKs and the OpenTelemetry Collector are actually used in production. To help close that gap, the SIG began collecting stories directly from end users—across industries, architectures, and company sizes. This post kicks off a new series focused specifically on organizations�…

Probably the craziest thing I've done in a while: Run Windows 11 in a Pod on my Kubernetes cluster, which consists of only Linux nodes, and have a fully functioning Windows that can read/write to an NFS mount on the network. This whole thing takes 45 minutes to even reach the desktop in the current setup. But 👏 It 👏 Works. All thanks to https://

In the context of a CPanel Softaculous-installed Nextcloud, what could it possibly mean that, regardless how I set the certificate through #CPanel, ak.modusresearch.com returns with the following clearly bogus certificate:
Common Name: #Kubernetes #Ingress Controller Fake Certificate
Organization: #AcmeCo
Not Before: Sat, 28 Feb 2026 15:37:53 GMT ?????
DNS Name: ingress.local
In what sort of twisted Universe would supplying such a thing make sense? Also interesting is the Not Before which was pretty much the moment I requested the page, but gave the same when asked an hour later.
