1and1.com is the worst web host company in the world. Not only are they unreliable, but they have also proven that they will screw over even their best customers. I don't expect them to be in business at this time next year.
The most current issue that I'm having with them is that they continue to make it difficult (seemingly impossible) to take back control of domains that I have bought and paid for. Most recently they have refused to transfer my charity domain, www.TheHairFarmer.com to my new registrar and host.
