Our DNS wouldn't have been down as we use DNS servers on separate networks (in virtually all cases, unless you have a non-standard DNS configuration) - it's possible your PC was relying on a DNS server on the same network which would've been unavailable, whereas perhaps the affected shared hosting server was ok a split second later.is tsohost and vidahost the same company? My website was just down aswell. Well the dns was, if i used ip directly it still worked.
