On September 26, 2021 at 4:38 PM ET Tucows’ Domains platform experienced intermittent issues while accessing Tucows Engineers were engaged and started investigating the issue.

The service interruption was caused due to an increase in the number of domain lookups performed.

At 2:20 PM ET, The Engineering team recovered the services by rate-limiting the increased domain lookup traffic to stabilize the environment.
