Question: If a web host is offering $10 dollar dedicated servers are they reliable?
Answer: The $10 dollar dedicated server is probably not reliable. The $10 dollar dedicated server offer, if it is being offered by a reputable web host, and not a scammer is probably not what you want. For a web host to be able to offer such a cheap dedicated server would require either using a really old server or they are selling you a VPS and saying its a dedicated server.
