This is all very interesting, but why couldn't FB just push an update remotely to solve this?
I've seen mentions everywhere that to fix this they required physical access to the BGP routers.
- ninkendo 5y agoHow would they push an update if they couldn’t reach their own network? My understanding is that if a bad BGP route was pushed and your whole network (typically accessed via VPN while the engineers WFH) is probably unreachable from any of you’re employees’ homes, it’s hard to get the right people on site to make a fix, or talk the remote hands folks at the date center through it over the phone. Troubleshooting is hard, troubleshooting while you have no access to your own network has got to be just that much harder.
