Increased Error Rate on S3 Cloudian

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.

Error rate has dropped. We are closely monitoring the situation. We are compiling a root cause analysis.

We are currently investigating an increased error rate for requests to S3 Cloudian in DE/FRA.
