This sort of thing happens 'often' ('XXX is not available, wtf?') should there be some set of troubleshooting steps followed, like a list of thing you'd do in order to show you'd troubleshot the problem and it wasn't "your problem"? Something along the lines of: o whois output o dig NS output o dig +trace output o 'downforeveryoneorjustme.com' says things are tango-uniform o other... reported such that others can either refute usefully or corroborate. -chris On Sat, Feb 18, 2012 at 4:46 PM, Israel G.
