Incident Date: June 5, 2022
Incident Number: PR-3206

On June 5, 2022 at 12:30 PM ET, Tucows’ Domains platform experienced intermittent service interruption impacting OpenSRS and Enom. During this incident users were unable to purchase domains, perform domain lookups, and there were delays in registrations and transfers.

The service interruption was caused by an unexpected behaviour on one of the storage devices causing API timeouts.

On June 6, 2022 at 6:54 PM ET, The engineering team increased the timeout configuration to reduce order processing delays. At 7:55 PM ET, they performed a code change and restarted the affected device to stabilize the impacted environments.

Tucows has an immediate plan to investigate the root cause of the unexpected behaviour. 

Tucows is reviewing the architecture to further prevent future interruptions.

Tucows is to review and enhance monitoring for better visibility and to address the issue in a timely manner. 

Thank you,

Tucows Engineering Team
