  3. resolved Nov 10, 2025, 04:48 PM UTC

    We want to share the following Root Cause Analysis: What happened: On the 6th of November, our Monitoring Team alerted us to increased error rates for requests to S3 Cloudian in DE/FRA. The increased error rate was caused by a network-level issue related to MTU settings lower than standard, causing intermittent issues for some connections. What we are doing to prevent this from happening again: On 11.11.2025, a fix will be rolled out to the affected network, which will correct the MTU settings permanently.
