Root Zone KSK Rollover Countdown Begins October 2026

On 11 October 2026, the global DNS root zone Key Signing Key (KSK) will rollover and begin using only KSK-2024. If your DNSSEC-validating resolver does not have KSK-2024 configured by this date, your network will experience total DNS resolution failures, cutting off Internet access for your users.

Your n8n Enterprise instance could log someone in as a completely different user — and that person's password would never even be checked. Here's what happened: n8n matched incoming JWTs to local accounts using only the `sub` claim, completely ignoring the `iss`

HTTP responses, ping, TCP ports and SSH command exit codes. No agent to install, no plugin to maintain, nothing to deploy on the machines you're watching. Hesklo probes from the outside on a schedule you set, and when something fails it follows the escalation flow you drew. It also tracks SSL expiry and response time trends, so you catch the slow creep before it turns into an outage.

Nobody told me TruFOS was installed during the FOS 9.x upgrade. I found it in the post-activity notes. A certificate. Three-year validity. No monitoring coverage anywhere in the stack. The switch keeps passing traffic when it expires. No fabric disruption. No SNMP trap. Nothing changes in Unisphere. Your SAN dashboard looks exactly the same the day after expiry as the day before. ⚠️ The only moment TruFOS announces itself is when you try to make a config change and the switch refuses it. No degraded state before that. No warning. Just a refusal, mid-activity, with no obvious reason if you don't know what you're looking for. Before FOS 9.x, this cert didn't exist. Nothing in the standard monitoring stack grew to cover it when it arrived. If you inherited this estate after the upgrade, you inherited a three-year countdown that nobody handed you. ✅ The fix is embarrassingly low-tech: pull the expiry date at upgrade time, document it, set a reminder 90 days out. That's the entire solution — because no tooling does it for you, and waiting for tooling means waiting until the switch tells you the hard way. I'm adding it to the handover checklist for this estate. Not because we hit the failure. Because we almost didn't notice the clock was running. What's your team's actual method for tracking cert expiries that arrived bundled with a firmware upgrade — calendar, CMDB, something else? #SAN #StorageEngineering #SRE #PlatformEngineering #FibreChannel
