Hot take: Telecom companies have the most untapped potential for edge computing - think AWS Wavelength but a compute platform - but none so far seem to be creating differentiated offerings (think Cloudflare workers being executed *down the street* from your users!)

At all.
Apparently they no longer even bother pretending to try.

CS Prof Al-Kiswany @SamerAlkiswany and his group have examined this common fault and have created a "Nifty" solution.

I was contemplating whether the Cloudflare incident could be cl***ified as a BFT or not.
Thread on the subject👇
tl;dr: Technically it is a BFT because "anything goes" with BFT. BUT: It's impractical as we can narrow it down into an Omission failure which is a simpler problem.

And the communication protocols required are very heavyweight, and hard to implement correctly (lol we think Paxos is hard). So do we really have to go down this route to handle Cloudflare's error?

@Cloudflare TL;DR: This was not a Byzantine failure. It was a lesser type of distributed failure known as "unreliable delivery", which is still a stronger type of failure than a "crash", which Raft consensus protocol is designed to handle well.

@alexstamos @Cloudflare This is a huge issue for local governments. When I was at NENA, we tried to get local 9-1-1 centers to require some minimal controls. The inability to buy without added complexity was a huge barrier. Almost as big as suppliers being uninterested in serving the <10k boxes market.

@gl***bottommeg Hcaptcha will cut down on the false submissions, while cloudflare/aws shield/etc (all cloud providers have their own offering) will cut down on the traffic. Sorry to hear they’re dealing with this. They also should read any bandwidth pricing charts ASAP and make sure they’re a-ok

@knoxthebadroo @chemipuu @furaffinity Which means Cloudflare’s servers are up, but FA’s are not. FA is the target.
Yes, traffic is supposed to flow through Cloudflare. But FA is the one down, not Cloudflare. The error even shows it’s on FA’s end.

@ittaia @Cloudflare @tlianza This is a great question. Pre-vote should have avoided the leader election disruption because the existing leader would have never stepped down. Perhaps proposals were getting stuck in limbo on the partitioned node, waiting for the election to complete? Or pre-vote was disabled.
