Good question and good suggestion.
It’s true that these are the same servers that had all the issues in June. Judging by the symptoms, I would say the current issue is also storage related.
But I have not received any information yet from iFastNet as to what is actually going on, how long this may take to fix or whether there will be any data loss.
If you’re OK with having to restore your website without access to your current files (like last time: database are unaffected), moving your domain to a different account is a good way to get your website up in a predictable time frame.
Like I said: I will update the topic as soon as I know more. If I had an estimate, I would put it there.
