I have two connections, a business-class DSL connection (100/10) and a residential cable connection (1000/50). Both ISPs in my area have random issues, and I really can not afford to have my service go down for hours at a time. It costs me a pretty penny ($135+$65/mo), but I have much better reliability and can balance traffic between them when they are both up (my home lab runs off the DSL connection as it has a static IP, but will fail over to the cable connection if it goes down. My personal systems, game console, etc. are the opposite).
