For a global company 1and1 is not very professional. They have lost all our files that were accumulated on their server for over a year, including the application package and informed us that there is no backup. It took 3 days before someone told us that they have lost all the files and will not be able to bring the site back. The customer support is the worst, they don't know anything, and once you ask them questions they don't want to answer they hang up on you (after you have waited on the line for 45min). Needless to say we are working on taking our business elsewhere.
