Support Needed for RCA about SQL DB Connection Issues Caused outage

Hi Raja,

For an official RCA of an Azure SQL Database connection outage, Microsoft Q&A users will not be able to check backend telemetry or confirm the platform-side root cause. You would need to check Azure Service Health / Resource Health first, and if the outage is not clearly explained there, open an Azure support request.

Please check:

1. Azure Portal > Service Health Look for any Azure SQL Database service issues around 04/28 in the affected region.

Azure SQL Database > Resource Health Check whether the database shows Available, Degraded, or Unavailable during the outage window.

Azure Monitor metrics / logs Review failed connections, DTU/vCore utilization, CPU, workers, sessions, deadlocks, throttling, and firewall/network changes during the same time.

Application logs Capture the exact SQL error numbers/messages, timestamps in UTC, client IP/app server, and connection retry behavior.

If you need a formal RCA for business/audit purposes, open a Microsoft support request and include:

Subscription ID

Server/database name

Region

Exact outage start/end time in UTC

Error messages/error numbers

Resource Health screenshots

Application connection logs
