Missing metrics on statuspageResolved Sep 11, 2026 · 0 minResolved

During the incident today we also noticed (belatedly) that the status page metrics updater had been failing because the status page API key had expired, oops.

Database troubleResolved Sep 11, 2026 · 2h 22mResolved

MySQL went down because our Ceph storage cluster filled up. That traces back to a Ceph security upgrade we'd just finished. The new version checks S3 upload signatures more strictly than before, and that exposed a bug in the S3 client our monitoring system uses: it doesn't sign one of the headers Ceph now requires. Its uploads got rejected, and instead of giving up it retried forever. Each upload is really several requests: the bulk data went through fine, but the small file that finalizes it kept getting rejected, so the data piled up without ever completing into anything usable. More than a terabyte of duplicate data accumulated in about half a day, more once you count replication overhead. A full Ceph cluster stops accepting writes from everything, and our database lives on the same cluster, so all three MySQL nodes crashed at the same time. Ceph was back as soon as we'd cleaned out the orphaned uploads. MySQL took longer: two of the three nodes had fallen too far behind to rejoin automatically, and their rejoin attempts took the primary down twice more before we fixed them by hand. The site was down a bit over two hours in total. Monitoring data from that window never got stored and can't be recovered. No other data was lost. The client library's bug is already fixed upstream, but the fix hasn't shipped in a release Mimir or Tempo use yet, so we moved that traffic to a connection where it signs everything correctly instead of waiting for it. --- [2026-09-11T21:51:21.978Z] (resolved) This has been resolved. The cluster is healthy again and the underlying causes have been resolved. --- [2026-09-11T19:49:43.326Z] (identified) The symptoms and immediate cause have been identified and remedied. Working on restoring the database cluster to a healthy state. --- [2026-09-11T19:28:46.093Z] (investigating) The database cluster is crash looping and/or starting up very slowly after a crash. We're investigating.

NTP Pool Status FAQ

Is NTP Pool down right now?

The verdict at the top of this page comes from the latest poll of the official NTP Pool status feed and refreshes automatically, so you are not looking at a stale cached answer. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead.

What should I do if NTP Pool is not working?

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until NTP Pool recovers.

How do I check NTP Pool uptime history?

PulsAPI tracks NTP Pool uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 99.84%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever NTP Pool changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.

How fast does PulsAPI detect NTP Pool outages?

PulsAPI reads the official NTP Pool status page. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead. Alerts reach Slack, Discord, Microsoft Teams, PagerDuty, or email within seconds of detection.

Does PulsAPI track individual NTP Pool components?

Yes. PulsAPI monitors 6 individual NTP Pool components, so you can see which service or region is affected instead of a generic "service degraded" banner.

Can I get alerts when NTP Pool goes down?

Yes. Create a free account and subscribe to NTP Pool: the free plan covers three services with unlimited email alerts and no monthly notification cap. Paid plans lift the monitor limit entirely (Pro and above do not meter how many vendors you watch) and route the same alerts into Slack, Discord, Microsoft Teams, PagerDuty and webhooks.

How do I report an issue with NTP Pool to the community?

Click "Report an issue" at the top of this page, pick the issue type and severity, and optionally add your region and a short note. Reports are anonymous and help other engineers spot NTP Pool problems early. Official status pages often lag real incidents by 10 to 20 minutes.

Is there a free way to monitor NTP Pool?

Yes. The free plan covers 3 monitored services with unlimited email alerts, permanently, so NTP Pool plus two more costs nothing. Every new account also opens with a 30-day Business trial (unlimited monitors, Slack alerts, SLA reporting) with no credit card.
