You also want a web host with 24/7 customer support—if not by phone, then at least by chat. Forums, knowledge bases, and help tickets are all well and good, but sometimes you just need to communicate with another human to get things ironed out as quickly as possible. That said, not all 24/7 customer support teams are equal. Companies like GoDaddy and Liquid Web boast incredibly knowledgeable and helpful customer support squads—a fact that we confirmed in our in-depth reviews of those web hosting services.
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
