Hi
Thanks for the update. It's been a bit vague on the updates front so far to be honest. Given that the last "official" update I saw was via an email (which in the few minutes where email could be collected for one of my email address did actually arrive) and the other update has been on here, hidden in the forums I can't say I am overly impressed.
Having worked in most aspects of IT Infrastructure from ISP, Retail IT and Defence, it is quite clear that you have either been seriously pwned, had a huge backend storage failure, or made significant changes to the backend systems that have resulted in an incompatability of data/systems resulting in this "temporary" loss of email availability.
Being more open with customers would be really helpful right now. Particularly a statement by a senior member of the team to the media would be a really good idea, rather than sinking further and further down a technological hole.
Instructions have been vague, error messages and "return to service" messages have been inconsistent (at one point you have a banner saying "return at 19:30" on the same page as having text that was updated to say "return at 21.30" when it was 22:00!)
I am currently in the position of having reset all my passwords for the main and all email accounts, but unable to log in to either webmail or via IMAP/POP3. The current message when visiting the mail.virginmedia.com page suggests complete removal or compromise of the accounts, but you are also saying this is a data availability issue (I am guessing the restore or rollback procedure is more complicated than expected or as untested as most large enterprises) which leads to further inconsistencies in the message you are sending to customers.
Get it together VM. It's really not good enough. Just fess up and stop being so childish.
