DNS provisioning bug impacted hundreds of thousands of domains. 
Enom, a domain name registrar owned by Tucows (NASDAQ: TCX), has apologized for a botched data center migration and a DNS provisioning bug that took down websites over the weekend.
The issue began on Saturday during a planned data center migration. Enom told customers several times that there would be a 12-hour block when they wouldn’t be able to register, transfer, or make contact updates to domains, or provision new mailboxes or SSL certificates.
Challenges in transferring the database led to a longer transition.
Worse, a bug in Enom’s new DNS provisioning system resulted in incomplete DNS records for up to 350,000 domains. This took many websites and email addresses offline.
Enom is a reseller registrar, which means many of the end users experiencing problems had to complain to their reseller, who, in turn, had to blame Enom.
Tucows has been working on combining the Enom and OpenSRS reseller platforms since it acquired Enom in 2017. It was an old, cranky platform by the time it was acquired. You could argue OpenSRS isn’t exactly modern, either. A spokesperson for Tucows said the data center migration was not part of consolidating Enom with OpenSRS.
