I have just read on Electrum's Twitter page [https://twitter.com/ElectrumWallet] a recommendation to use electrum.blockstream.info as a server instead of having the server selected automatically.

Q1. What is this supposed to be good for? Occasionaly Electrum is slow synchronizing at launch, but otherwise, as far as I'm concerned, it's pretty much problem-free the way it's set-up.

Q2. Slight problem — this electrum.blockstream.info server is nowhere to be found in my server list...
