Looking forward to read about the postmortem analysis of this outage, and whether this operator had single points of failure.
I wonder if it will be anything like the Rogers outage in Canada. A bad software maintenance update made their infrastructure malfunction and so many people were offline from a few days to a week.
Yeah sounds like it was something similar. CloudFlare showed spikes in BGP announcements (the Border Gateway Protocol - basically how each network node knows it's neighbours and the route through that neighbourhood) when the system went down. So Optus stopped telling the world it existed and everything updated around it, shutting it out from the internet.
It may just be a coincidence but my work voip, which is non Optus, went down for an hour two days ago. My csm software is in the cloud and uses an sms gateway, with a different company and provider. It went down twice yesterday for a few hours. I don’t recall the last time that happened. I wonder if there was some underlying telecoms issue that undermined them all at different times.
