I had the same problem with failed repositories and like maya once I changed the DNS settings to the OpenDNS servers everything started working again. I had also been having problems with Foreca not updating but this too is now OK. So what changed out there, because previously having auto DNS was no problem? Judging from other forums I have looked at this is quite a widespread problem and maybe needs a lot more publicity. Not everybody is a Linux guru, we are just mobile phone owners. Same with non-availability of PR1.2 for people who have Vodaphone 205 build even though we bought generic phone from - in my case - Expansys, and I am on O2. I do not fancy risking bricking it by trying to flash build 203, and I worked in IT for 20 years.
