The plans start at $70 for 100 Mbps upload and download speeds to $100 for 250 Mbps and $250 for 1,000 Mbps. There's also been an increase in the number of static IP addresses a business can have, up to 13. Small businesses that are eligible for these plans, like those in Charlotte can go ahead and sign up for the new plans, but if you're not located there you can check and see Google's list of upcoming Fiber areas to see when it might be coming to you.
Small business owners in Kansas City, Provo, Austin and Nashville can sign up until July 31st as part of the Early Access program for Google Fiber, and starting on August 1st they can take advantage of Early Access pricing for a year or one of the new plans available to them. Hopefully these rollouts continue for the foreseeable future for residential users as well!
