According to the availability tool, Sonic Fiber became available at my address today (woohoo!). I know that as an existing customer I don't have to put in a request to switch to the new service, so I was wondering how long it would be until I'm contacted by Sonic to make the switchover?
You should get an emailed invitation to schedule your migration in the next couple days. (If you don't, please let me know!)
But meanwhile, you can use the Member Tools to kick this off, that is where the email would direct you. Here: https://members.sonic.net/connections/serviceupdate/
