When your mail server connects to a recipient server to deliver email, the very first thing it does after the TCP connection is established is introduce itself. That introduction happens through the EHLO command (or its older predecessor HELO), and it looks like this: That hostname in the EHLO line is your SMTP banner. It is what your server claims to be.

The Start of Authority record is the first record in any DNS zone file. It's the record that says "this zone exists, this is the primary nameserver in charge, and here are the timing rules that govern how this zone behaves." A full SOA record looks like this when you query it: Each of those numbers does something different. The one that triggered your warning is the Expire value, the fourth number. In this example, 1209600 seconds, which is exactly 14 days.

Kerberos is a secure network authentication protocol that allows users and systems to prove their identity over a network without sending passwords in plain text. It is widely used in enterprise environments (for example, in Windows domains) to enable single sign-on (SSO). At its core, Kerberos uses a trusted authority called the Key Distribution Center (KDC) to issue encrypted “tickets” that verify identity.

Over the weekend, my own site went down and Oh Dear didn't catch it. The origin server had fallen over, but Cloudflare happily kept serving the cached HTML. Everything looked fine from the outside. Embarrassing. Scratching our own itch here, we just shipped magic variables: short placeholders you can drop into your monitor URL, request headers, or POST payload. Right before each check, we replace them with fresh values, so every request is unique enough to slip past any cache and actually hit your origin.

On May 14, 2026, users across multiple regions began reporting problems with Slack, including messaging failures, sign-in issues, and problems loading attachments and images. While the outage did not affect every user, reports quickly showed the issue was widespread enough to disrupt business communication for organizations around the world. StatusGator identified the incident through customer outage reports and triggered an Early Warning Signals alert at 14:21 UTC.

IncidentHub's latest product updates include a new Business plan with Teams support, early outage detection v1, and more integrations with ticketing systems. The public status now includes a disable feature. As before, many features are driven by feedback, and I am grateful to all our customers who have shared their feedback with us.

OpenTelemetry has become the default way to instrument applications and ship telemetry. The hard part has never been the data model. It’s been picking a backend that handles OTLP without quietly turning into a per-metric bill or a black box that swallows your data. Netdata is a native OTLP backend.

The discussion around AI in infrastructure and operations has become increasingly model-centric. Teams want to know what model a platform uses, how current it is, how much reasoning capacity it has, and how quickly it can be updated as the model landscape shifts. Those are reasonable questions, but they tend to arrive too early. In production operations, the more consequential question is what happens to the data before any model is asked to interpret it.
