Interesting that they published stuff about their BGP setup and infrastructure a few months ago - maybe a little tweak to roll backs is needed.
"... We demonstrate how this design provides us with flexible control over routing and keeps the network reliable. We also describe our in-house BGP software implementation, and its testing and deployment pipelines. These allow us to treat BGP like any other software component, enabling fast incremental updates..."
- pbhjpbhj 5y agoSurely Facebook don't update routing systems between data centres (IIRC the situation) when they don't have people present to fix things if they go wrong? Or have an out-of-band connection (satellite, or dial-up (?), or some other alternate routing?). I must be misunderstanding this situation here. [Aside: I recall updating wi-fi settings on my laptop and first checking I had direct Ethernet connection working ... and that when I didn't have anything important to do (could have done a reinstall with little loss). Is that a reasonable analogy?]
