.COM - Domain Availability Lookups returning incorrect data
Incident Report for OpenSRS

Incident Date: September 28, 2020
Incident Number: PR-1371

On September 28, 2020 at 1:54 PM ET we experienced intermittent issues with Tucows’ Domains platform where Domain Availability Lookups were showing domains as taken when available. Tucows Engineers were engaged and started investigating the issue.

The service interruption was caused due to the caching issue retaining incorrect data. 

On October 1, 2020 at 1:13 PM ET, The engineering team migrated the services from the legacy system and brought the services online on the new Domain Lookup System to restore them successfully.

Tucows is to review and enhance monitoring for better visibility. 

Tucows has moved all services to the new system and will be decommissioning the legacy system.

Thank you,

Tucows Engineering Team
