Well its not a fault as such switching servers, just an upgrade that takes it down, but what throws a spanner in the works is the actual VPS suppliers site was also down when I 1st noticed as I checked nameservers to see where it sat, so you could be right aswell but they didnt admit to it, only a mod will answer really, but guess the site has become so popular its outgrown the VPS to the degree it needs something more capable, speculating but stands to reason.
