Sonic.net

I'm thinking about getting a one line fusion service from Sonic. I currently have a 6mbps on my second line with ATT. I just want to know how much down time should I expect during the switch?

Typically, when switching from AT&T to Fusion, there is almost no downtime. Once the install time comes, it is usually back up by the time you get the equipment hooked up and router configured (if you have one). It can, in rare cases, take up to a few hours.
