Well there are the upgrades and server moves going on right now for the past two months.
I did see that there are upgrades taking place, and thought it was probably a case of bad timing that I happen to sign up for a new account, never having heard of x10 before, right in the middle of this upgrade project :\
However, the latest news posted 22 hours ago states that "all new hosting accounts should be all set", and goes on to imply that the accounts affected by the project are those created prior to March 13th. As I just created my account yesterday, I thought my account might not be adversely impacted. I'm willing to accept that I am impacted, but from all I've heard/seen up to this point, it isn't clear to me that the answer here is to "wait it out".
Thanks for the advice though, I do appreciate it. Since x10 is the first "other" web host I'm testing, I guess my next step will be to find yet another and try it again. I'll report back here what happens, and see if there are any other ideas, depending on the outcome.
