We had a couple of reports that Telstra (Australia) was down earlier today. Still not sure what the problem was, but to Telstra's credit they are using Twitter to keep their customers informed. Follow them at http://twitter.com/Telstra.

UPDATE - Looks like it might have been a DNS maintenance problem. Some details are here. Thanks for the pointer to that page, Mike!

It looks like their international routes were out. The primary symptom was no DNS, because no route to root servers. Ping was available to Australian carriers, but no route out of the country.
