Am heutigen 1. Oktober 2020 durften Anwender des Microsoft-Diensts Outlook.com eine weltweite vierstündige Störung durchleben. Folgt quasi auf den letzten Ausfall vor einigen Tagen.
Anzeige
Zum 28./29. September 2020 gab es die letzte Störung von Microsoft 365 – ich hatte im Beitrag Störung bei Microsoft 365 (28./29.9.2020) berichtet. Heute Früh hatte ich auf Twitter die Meldung zu einer weiteren Exchange Online/Outlook.com-Störung gelesen (und vorher einen Hinweis, dass es nur Indien beträfe bemerkt – daher greife ich es erst jetzt auf).
We've received reports of users experiencing issues accessing their Exchange Online accounts via Outlook on the Web. Our initial investigation indicates that India-based users are the primarily impacted audience. Further details can be found in your admin center under EX223208.
Ich habe eben mal auf allestoerungen.de nachgeschaut, die Störung bei Outlook .com war auch in Deutschland deutlich und dauerte ca. 4 Stunden.
Outlook-Störung (1.10.2020)
Microsoft schrieb dann im Twitter-Kanal mehrere Folge-Tweets:
We've collected additional data from the affected infrastructures to determine impact to our Exchange online protocols. Additionally, we've identified this issue to be affecting users worldwide. Further details can be found in your admin center under EX223208. (Link)
We're reviewing recent changes to our service to further determine the cause of impact. Users may experience problems with various Exchange Online protocols including Outlook desktop, mobile devices as well as those dependent on REST functionality. (Link)
We've determined that a recent configuration update to components that route user requests was the cause of impact. We've reverted the update and are monitoring the service for recovery. (Link)
Rollback has mitigated impact for the affected features in SharePoint and Microsoft Teams (SI#MO223247). For impact to the Exchange service (SI# EX223208), majority of the users are seeing recovery and we're taking measures to ensure full recovery for all our users worldwide. (Link)
Mit anderen Worten: Eine Konfigurationsänderung war verunglückt und hat Outlook.com weltweit aufs Kreuz gelegt. Nach einem Rollback klang die Störung wieder ab. Inzwischen sollte es aber wieder weitgehend funktionieren. Auf der Office-Statusseite wird jedenfalls keine Störung angezeigt. Ergänzung: Netzwelt hat hier eine Karte der betroffenen deutschen Regionen veröffentlicht. Und The Verge behandelt das Thema hier, bei heise gibt es hier einige Infos.
Ergänzung: Blog-Leser Andreas P. hat mir die betreffenden Status-Informationen zum Vorfall: EX223208, betroffener Dienst: Exchange Online, betroffenes Feature: Access, aktueller Status: Dienst wird wiederhergestellt bereitgestellt (danke). Hier der Auszug.

Title: Users can't access Exchange Online
User Impact: Users may be unable to access Exchange Online using multiple protocols.
More info: This is an incremental update to provide the latest status on the issue.
Current status: While our telemetry indicates that impact has been mitigated for the vast majority of previously affected users, we're continuing work aimed at ensuring the service remains stable and resilient. We're restarting portions of infrastructure that continued performing below optimal thresholds after the update was reverted. This action is part of our ongoing traffic-management optimization procedures to alleviate the remaining impact. Please reference the post from Thursday, October 1, 2020, at 2:08 PM UTC for complete details on this event.
