On September 12, 2024, at 4:45 a.m. PDT, Zscaler Digital Experience (ZDX) detected a significant and sudden decline in the ZDX Score for Microsoft 365 services. Our analysis revealed elevated network latencies for Microsoft 365 services, indicating a Microsoft outage. The ZDX heatmap vividly showed the extent of the impact. This observation aligns with a Microsoft post on X.

ZDX found a Microsoft outage and its cause. This made our customers feel safe that the problem was in one place and on a certain network, which prevented big business disruptions and overwhelming IT teams.

Depending on the time and filters selected in the dashboard, the score will adjust accordingly.

From within ZDX, service desk teams can easily see that ‌service isn’t just bad for one place or user. They can quickly start looking into the cause of the problem.
