I've just had two new sponsors show up with a pair of UK mirrors.
mirror2.uk is thanks to UK Broadband, who have graciously given me access to a few hundred megabits of traffic and space on an ESX server.
mirror3.uk (due to be turned up today!) is thanks to a private donor named Alex who has given me a server in his colocation space and up to a gigabit of traffic.
Shiny! Thanks to you both.
