Incident S1 CORP-34512 on Sigfox network
Incident Report for UnaBiz
Resolved
This incident has been resolved.
The incident was caused by a relative drop in performance of the application during a burst of callbacks, which in turn triggered an error/retries effect saturating its capacity.

Corrections have been carried out to fix weaknesses identified at the origin of the performance drop.

Additional capacity has been provisioned to add further margin against similar performance issue and against impact of escalating load due to a snowball effect.

Our alerting system has been further strengthened to accelerate our responsiveness.
