It's not surprising to find bugs and errors during early access. You'd be kind of crazy to assume that something wouldn't go wrong because issues happen even on normal patch releases.
A lot frustration comes from the fact something so "game breaking" has happened so early into the main quest and it feels like little is being done about it. Regardless of server congestion, players (paying customers) at least want an illusion that something is being done. Pretty much SE's "fix" is to have you constantly try to get into the instance because things are technically working on their end.
I'd be ok with the servers temporarily being unavailable and then reopening data centers on a schedule since it's a physical limitation causing the problem. I understand that it would suck for anyone who isn't apart of early access, but this problem is only going to get worse throughout the weekend and let's face it...Hell will break lose on Tuesday if this problem still exists.
