Notes

• Data sourced from Dynatrace problems for the last 24h, sorted by latest start time.
• Several incidents involve blob-writer related services and a recurring slowdown/error pattern.

Next steps (suggested)

• Correlate with recent deployments/config changes for func-blobwriter-64346 and stblobwriterfunc1234.
• Check Azure App Service metrics (CPU, memory, thread/connection counts) around the above windows.
• Review dependency health (storage/queues) and retry policies.
