We want to inform you about two brief service outages affecting Mercury today.

Incident Details

Duration

  • First outage: 10:21 AM to 10:34 AM CET (12 minutes)
  • Second outage: 10:46 AM to 10:54 AM CET (7 minutes)

Impact

During these periods, the service returned a "503 Service Temporarily Unavailable" error.

What Happened

Our preliminary investigation indicates that the outages were caused by a sudden loss of connectivity within our database cluster. The automatic failover mechanism did not select a replica to serve the application, resulting in temporary service unavailability.

Current Status

The service is currently operational, and we are closely monitoring it. Our team is actively investigating the root cause to ensure the reliability of our failover mechanisms and prevent similar incidents in the future.

We sincerely apologize for any inconvenience this may have caused.
