Optus NBN appears to be just a DNS issue, people reporting their NBN working with third party DNS provider.
I strongly recommend not using telco for DNS regardless.
FYI for those that don't know, Optus services down nationwide, effects 10 million customers as well as payment terminals, Metro trains are also partially down.
Optus is so shit. How hard is it to keep a DNS server running?
Rule 1) It's always DNS. Rule 2) If it's not DNS, it's a new DNS failure mode you're not yet familiar with.
Not a good year for Optus
I’d love to know how it took metro trains down. Do they not have and redundancy or a DR plan for something that appears to be mission critical ?
If a router or switch doesn't detect an outage properly, or is misconfigured, you are still gonna have a bad day regardless of redundancy.
