I woke up to find 1and1.com had deleted all of my databases(running multiple live sites). How did this happen? I paid to upgrade to a dedicated server from a regular package. I continued to use my databases for months. Suddenly, 1and1 delete all of my databases, taking my sites offline. They also took more than a week to perform the "upgrade", in which they apparently did absolutely nothing. They sure as hell didn't move my databases.
I am assuming - you paid to upgrade to a dedicated server, when after you moved your files ( i assume) you continue to use your old hosting account, with 1&1 and after they deleted your old account due to non payment, because you already upgraded , your sites are no longer working. correct?
I paid to upgrade to dedicated, continued to use the standard DB system. Suddenly, they delete the databases without any warning. Not for non-payment, as part of the their upgrade process...
dedicated = separate server they will have to MOVE the actual database to new server { as opposed to just changing permissions to a new account} i don't think they will be able to do it, , because most of the time, databases etc are password protected etc ( access passwords, they are sometimes separate from hosting login url) { i am not referring to the login to phpmyadmin and downloading sql file.} that anyone can do open the support ticket, and ask them whats the issue clearly
Who was responsible for the migration of your data to your dedicated server? If 1&1 was the one responsible...Did they have moved your databases to your dedicated server? if yes, you can check your websites configurations files to see if the login/pass/server creditentials fit with your new dedicated. You don't have any backups of your database?
