Notes:

• Source: Dynatrace problems from last 24h.
• Many issues relate to function services with failure rate spikes and response time degradations.

Action proposal:

• Investigate recent deployments or configuration changes around func-blobwriter-64346 and stblobwriterfunc1234.
• Review error logs for POST /api/write_blob.
• Validate performance baselines and auto-scaling for the affected services.
