Störung: Microsoft Teams rumpelt (16./17.3.2020)

Bei der Cloud-Lösung Microsoft Teams hat es zum 16. März 2020 wohl ziemliche Hakeleien gegeben. Die Cloud-gestützte Collaborationslösung aus dem Haus Microsoft war plötzlich nicht mehr zu gebrauchen. Ergänzung: Auch am 17. März 2020 klemmt es.

Das es mit Microsofts Cloud-Lösungen wöchentlich mehrfach irgendwo hakt, lässt sich an inzwischen zahlreichen Blog-Beiträgen nachlesen. In Zeiten von Coronakrise und Home Office setzen möglicherweise viele Nutzer genau auf diese Collaborationslösungen. Die Macher von Slack haben gerade einen Bug gefixt, der die Übernahme eines Benutzerkontos ermöglicht hätte (siehe diesen Artikel auf Bleeping Computer).

Bei Microsoft war das zumindest gestern kein Problem, denn dort konnte man sich als Benutzer (wenn man zu den Pechvögeln gehörte) unter Teams schlicht nicht mal mehr anmelden. Blog-Leser Daniel S. schickte mir zum gestrigen Abend eine Mail:

FYI

Die MS Cloud dreht wieder komplett am Rad heute. Vermutlich steigen heute alle ins Home Office ein – ausgerechnet jetzt funktioniert kein Teams.

Aktuell sind 7 Rot Meldungen im Admin-Portal

Daniel

Auf Nachfrage hat er mir noch den nachfolgenden Screenshot des Admin-Status geschickt, die eine Störung zeigt.

Teams-Status

Die Auflistung zeigt zwar viele grüne Häkchen – aber das sind Problemchen, die das Support-Team im Laufe des Tages behoben hat. Ergänzung: Gerade habe ich noch einen Status bekommen, dass es vor allem Europa betrag.

Martin Geuß hatte es bereits zum Vormittag auf Dr. Windows als Digitalisierung am Limit: Microsoft Teams kämpft mit Aussetzern thematisiert. Inzwischen sollte das Problem weitgehend behoben sein. Blog-Leser Andreas P. hat mir die Statusauszüge aus dem Administrator-Dashboard geschickt:

Kommt natürlich zur Unzeit, wenn mehr Leute diesen Dienst nutzen möchten. War jemand betroffen?

Neue Störung zum 17. März

Ergänzung: Auch am 17. März 2020 klemmt es. Zumindest entnehme ich dies dem aktuellen Statusbeitrag des Service-Teams auf Twitter.

Hier noch die Statusmeldungen vom 17. März, die mit Blog-Leser Andreas P. zur Verfügung gestellt hat.

Title: Teams messaging functionality issues

User Impact: Some users may have been unable to send and receive messages or schedule meetings and live events.

More info: Additionally, some users may have been unable to create teams and update team memberships within the Microsoft Teams service.

Current status: We connected the service to alternate, healthy infrastructure to mitigate impact for the affected users. Additionally, we applied a mitigation to address the caching issue that resulted in impact. Our investigation determined that the impact that occurred on Monday, March 16, was symptomatically the same as the impact from Tuesday, March 17, but with a different root cause. We’ll publish a Post-Incident Report within five business days to provide additional context into the root cause of these problems.

This communication will remain open to provide additional updates in the event this issue reoccurs.

Scope of impact: Our telemetry indicated that this issue affected some users hosted within the Europe region.

Start time: Monday, March 16, 2020, at 2:20 PM UTC

Root cause: On Tuesday, March 17, a caching issue occurred within a component of the service that supports the messaging feature, resulting in impact.

Root cause: On Monday, March 16, a downstream service was experiencing latency when processing requests, resulting in errors within the service that processes chat functionality. We’re actively determining what caused the downstream latency and putting in any corrective measures required.

    Ich wollte gestern mehrfach einen neuen Vertrag mit neuen Zugangsdaten ins Volume Licence Service Portal bringen, bin aber den ganzen Tag daran gescheitert (den angeblich zugesandten Code zu empfangen).
    Bei bereits bestehenden Zugängen gabs das Problem nicht. (Auch die Codezustellung funktionierte dort – nachdems im AntiSpam freigegeben wurde).

    Vielleicht hats ja mit der hier gemeldeten Thematik zu tun.

    an, um Störungen zu sehen.

    Teams scheint nicht erfasst zu werden.

    Warum eigentlich?
