Degraded performance on us-east-1 cell caused by AWS outage
ResolvedDegraded performance27 hours 24 minutes
  • ResolvedUTC
    This incident has been resolved.
  • IdentifiedUTC

    This morning AWS outage has impacted all our tenants hosted on the us-east-1 region.

    Impact is limited as the application remains mostly available, but integration syncs and datasource monitoring might not be running properly.

    The issue is currently being mitigated by AWS.

Downtime on eu-west-1-a cell
ResolvedMajor outage92 hours 17 minutes
  • ResolvedUTC

    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.

  • MonitoringUTC
    Remediation has been successfully applied. We are closely monitoring the status of the cell and investigating its root cause to prevent it from happening again.
  • IdentifiedUTC

    We are continuing to work on a fix for this incident. Remediation is being applied.

  • InvestigatingUTC

    We're investigating reports of degraded performance across the Sifflet web applications.
