What happened
We added object storage devices to the de-2.platform.sh region. This change unexpectedly caused I/O performance issues.
Customer impact
Affected environments experienced slower than usual read and write operations, or their writable mounts suddenly became read-only.
Resolution steps
The response team added more object storage, allowing the data recalibration to complete faster, and to provide more I/O throughput to affected projects. Read-only mounts were manually investigated and recovered.
