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.

That's our ruleset on Outages; I repost it every so often (optimally
monthly, though it's not automated yet...)
