The official Electrum website (
https://electrum.org/) has been down for a while. I know there could be a maintenance or something like this... anyway, I just like to know if everything is ok or some attack is happening...
I checked the twitter page
https://twitter.com/electrumwallet and It seems like there is nothing regarding this, I'm going to assume It has something with the host and not really an attack.
Electrum is open source and available on Github so I don't see why would someone take it down , If it comes back online just make sure to check the downloads signatures (you should do that even when It's not taken down just in case) before downloading or wait for an announcement from ThomasV.
