2020 July 10
Around 14:56 UTC, the site stopped responding to any requests from the outside, even ICMP ECHO (ping). The site thus appeared to be hard down, like the crash we experienced on 2020-06-30. I even tried logging in to Fourmilab, which is in the same AWS data centre, and was unable to ping RB. While I was preparing to bring up the AWS EC2 console and try rebooting the instance, it "got better" and everything returned to normal. The WordPress dashboard showed nothing out of the ordinary and the site responded normally. I checked /var/log/messages around the incident and it was completely nominal. My only guess is that some Dilbert (or Fritz) in the Frankfurt AWS data centre was fiddling with cables and briefly disconnected the server running our site from their internal backbone. There were no persistent consequences from the outage, which lasted less than two minutes. I ran a Garback just in case something further happened so as not to lose recent firewall additions. I guess you can say the site was briefly "on the Fritz".
