Downtime on eu-west-1-a cell
  • Resolved
    Resolved

    This incident has been resolved.

    Downtime started at 2:10pm CEST on Friday the 8th of August and was over by 2:35pm CEST on the same day, and only affected our eu-west-1-a tenants.

    The cause of the downtime was an unavailability of the database caused by a sudden surge in the database usage, that occurred at an unexpected speed and magnitude. Our auto-scaling and monitoring systems failed to react in time.

    We're improving our monitoring and auto-scaling to prevent such downtime to happen again and investigating the component that might be responsible for this unnecessary database load.
