.blog registry handover did NOT go smoothly

The transition of .blog between registry back-end providers ended up taking six times longer than originally planned, due to “a series of unforeseen issues”.

Registry Knock Knock Whois There today told registrars that the move from Nominet to CentralNic took 18 hours to complete, far longer than the two to three hours anticipated.

An “unexpected database error” was blamed at one point for the delay, but KKWT said it is still conducting a post-mortem to figure out exactly what went wrong.

During the downtime, .blog registrations, renewals, transfers and general domain management at the registry level would not have been possible.

DNS resolution was not affected, so registrants of .blog domains would have been able to use their web sites and email as usual.

The migration, which covered roughly 200,000 domains, wrapped up at around 0800 UTC this morning. It seems engineers at the two back-end providers, both based in the UK, will have been working throughout the night to fix the issues.

KKWT reported the new CentralNIC EPP back-end functioning as expected but that several days of “post-migration clean-up” are to be expected.

Eighteen hours is more than the acceptable 14 hours of monthly downtime for EPP services under ICANN’s standard Registry Agreement, but below the 24 hours of weekly downtime at which emergency measures kick in.

CentralNic already handles very large TLDs, including .xyz, but I believe this is the largest incoming migration it’s handled to date.

KKWT is owned by Automattic, the same company as WordPress.com.
