Temporary Service Interruption

Major incident BSS Sites Azure US region

Updates

Retroactive

On 01 December, 2025, between 15:22 – 16:02 UTC, one of our application servers experienced network connectivity failures that resulted in approximately 40 minutes of random failures for BSS Portal application. While our load balancer is designed to automatically reroute traffic to healthy servers, in this case the switchover process did not complete in time, leading to a brief service interruption. During this period, users may have experienced difficulty accessing BSS Portal, issues during navigation or execution of actions. Service was fully restored at 16:03 UTC, and since then all systems are operating normally.

Impact

  • Users were not able to login to BSS application.
  • Some users experienced slower than usual performance.
  • A portion of requests failed to load during the incident window.
  • The issue was resolved without further actions by our staff within 40 minutes

What We’re Doing Next

To prevent this from happening again, we are:

  • Optimizing our internal processes for removing quicker problematic servers from work load during similar incidents.
  • Optimizing load balancer health probes to include more internal health checks.

Current Status

All systems are operating normally. No further problems have been detected since resolution.

We apologize for the inconvenience this caused and thank you for your patience and understanding.
