With Electrum server nature which allow anyone to connect (exception for blacklist known IP used for DDoS/malicious acitivty), it's over for now.
Attacker will find another way as long they have money and will to do it.

Out of fun these days i decided to run my own Electrum server, since i have a full bitcoin node synced and all... And i got one called "Electrum Personal Server", Lo and behold, it made the Electrum wallet work like Bitcoin Core or better. So if the public servers go down i could always use mine now. Next i could try running Electrumx or the other one, not sure which is better, but if i do, i would run it only over tor as a hidden service...
it probably is better if you run ElectrumX since it is the most used and because of that it has least amount of bugs. but you shouldn't ignore the alternatives either. the only thing to consider when running an alternative is to check if it is actually an "alternative implementation" or is it the same thing translated into another programming language or if it is a simple wrapper around the main one with additional features.
