Gemessene Verfügbarkeit

Neunzig Tage Messwerte, Tag für Tag.

Jeder Balken ist ein Tag. Verfügbarkeit ist der Anteil erfolgreicher Fünf-Minuten-Prüfungen – gemessen vom externen Monitor, nicht von HansaChat selbst. Das Verfügbarkeitsziel der Servicelevel-Vereinbarung gilt pro Kalendermonat; die Tagesbalken zeigen rollierende 30- und 90-Tage-Fenster für die laufende Übersicht.

   HansaChat Status Alert Landing Page has been DOWN for 3 consecutive checks. Affected services: Landing Page Last error: HTTP 504 Time: 2026-09-29T08:00:39.412Z

   Post-Mortem

   Summary On 2026-09-29 both the chat API and the landing page were unavailable for about 30 minutes. Automated 5-minute checks recorded continuous HTTP 502/504 gateway failures between 07:50 and 08:25 UTC. Root cause An IONOS Cloud incident: partial connectivity degradation to the control plane affecting Kubernetes operations. See https://status.ionos.cloud/incidents/zprjxl2b1kmy for details. No defect in HansaChat application code was involved. Impact Around 30 minutes of downtime for both the chat API and the landing page; all incoming requests failed with HTTP 502/504 gateway errors. Resolution Service recovered automatically once the IONOS incident ended. Monitoring confirmed full recovery at 08:25 UTC; no HansaChat-side intervention was required.

   HansaChat Status Alert Chat service has been DOWN for 3 consecutive checks. Affected services: Chat API Last error: HTTP 502 Time: 2026-09-02T09:15:53.599Z

   Post-Mortem

   Summary The real-time chat API was unavailable for about 15 minutes on 2026-09-02 (09:05-09:20 UTC). Requests to the chat API returned HTTP 502 because the queue processor worker could not start. The landing page stayed reachable apart from a single failed probe during the same window. Root cause HansaChat started as a startup, and the initial credentials-injection implementation fetched credentials from the upstream API on every request, without any caching. During an unusually intense development day more than 1,000 items were requested in a short window, which exhausted the upstream API's rate limit. Without credentials available the queue processor worker could not start, which took the real-time chat API down with it. Impact Roughly 15 minutes of real-time chat API downtime (09:05-09:20 UTC); queued message processing was stalled for the same window. The landing page was not materially affected. Resolution Service recovered once the upstream rate limit window reset (09:20 UTC). Credentials injection now uses an in-cluster cache, so a temporary upstream rate limit can no longer prevent worker startup.

   HansaChat Status Alert Landing Page has been DOWN for 4 consecutive checks. Affected services: Landing Page Last error: The operation was aborted due to timeout Time: 2026-08-14T18:45:41.129Z

   Post-Mortem

   Summary The landing page was unavailable for about 20 minutes on 2026-08-14 (18:35-18:55 UTC). Chat services recorded no downtime during the incident. Root cause The underlying Kubernetes node failed and its pods were rescheduled. Traefik kept routing correctly to the old pods, which were still serving while being drained. After the deployment of the new landing version, Traefik could not find the new pods' IP addresses, so landing traffic was sent to endpoints that no longer existed. Impact Landing page downtime of roughly 20 minutes. No chat downtime was recorded.

Unabhängiger Monitor

So gebaut, dass er weitermisst, wenn HansaChat selbst nicht erreichbar ist.

Diese Statusseite wird zusammen mit dem Produkt betrieben. Die Messungen stammen von einem separaten Worker auf Cloudflare, der unabhängig von HansaChats DNS, Hosting-Region und Infrastruktur ist – wenn hansa.chat einmal nicht erreichbar ist, prüft der Monitor weiter und seine eigene Seite antwortet weiterhin.
