Re: Not Gamma
Another ISP had downtime this week - their primary BT link failed, then instead of fixing it BT somehow cut the backup link by mistake. On the backbone, they use multiple bonded 10G links (up to 32 of them?) so a lot of those links will be serving multiple ISPs at once, including their own retail arm.
I wonder if someone at BT deleted the wrong thing? Redundant hardware only takes you so far - even with the most resilient system there is, tell the system "route all traffic for address range X to the bitbucket" and everyone at X is stuffed. Like the Royal Bank of Scotland fiasco, when their very reliable and secure mainframe was mistakenly told "delete all transactions" - so it reliably and securely deleted all transactions, leaving a reliable and secure disaster while they figured out how to reverse it.
