always remember that just because some website like ccn publishes something it doesn't mean it is correct. majority of these sites are only creating clickbait nonsense to increase their traffic.
Electrum is down as a result of a massive DoS attack.
Electrum is not a centralized server to go down. there are many individual bitcoin nodes with specific setting for Electrum, someone has been targeting these nodes so they are less responsive lately but it is not completely "down". you still can connect to some of the nodes and sync.
i just did it right now, it took about 15 seconds to find servers and sync without an issue. give it a try yourself and then trust the bullshit articles you read online.
Is it possible to recover my wallet using the master seed OR by exporting the private keys to any of the following wallets:
it will not work using your "seed" because no other wallet is compatible with Electrum. and also remember that if you imported your seed, master private key or any single private key in any of those wallets specially the closed sourced ones be sure that your Electrum wallet is going to be compromised.
