Incident Number: PR-2392
On September 26, 2021 at 4:38 PM ET Tucows’ Domains platform experienced intermittent issues while accessing hover.com. 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.
On September 27, 2021 at 10:27 AM ET, Tucows’ engineering team increased the severity of the incident after we observed the external impact.
At 2:20 PM ET, The Engineering team recovered the services by rate-limiting the increased domain lookup traffic to stabilize the environment.
Tucows has implemented a permanent solution to prevent further interruption.
Tucows is to revise the architecture to further improve the overall security against high volume of traffic.
Thank you,
