[AusNOG] Optus outage last night?

[Mark Foster]

I'm in the ISP's DNS camp. If you want expected/predictable connectivity 
+ behavior that's usually the best choice.

If you can't trust your ISP DNS 'most' of the time, you need another ISP?

Clearly incidents happen, and knowing how to change to an alternate can 
give you perhaps subobtimal service - which is better than no service - 
but if your ISP is any good they should be able to keep at least one of 
their resolvers functional?

Mark.
