My favorite outage when I worked for a voip company was when one of our tech support people told a new customer that she needed to ‘add our ip address to your router’, meaning add it to the firewall whitelist, but she repeated that verbatim to the telco tech who misunderstood and then escalated her way up the chain at a major telco until some engineer with the wrong rights said ‘fuck it’ and updated bgp to route all of our traffic down her T-1 line. That was a fun conference call, and listening to the lady on the phone I could see how the engineer got to that point.
