Ok, hard to explain, .co.uk owner since 2005 (expires in 2017) registered the .uk in 2014, which subsequently expired and was due to drop today. Have been chasing it, then noticed my system stopped. Checked the whois and the .uk is now showing the domain back in the 'right of registration' status, since 20:30 this evening. How is that even possible? Why would a registered .uk (not right of...) suddenly return to that status; Nominet don't allow it, and certainly not at this late stage in the day.
