I have the same problem, unfortunately, down in 94621. The web tool puts me at 12,055ft from the local office, which gives me speeds consistently hovering around 0.85mbps. Working from home on web-based projects, this makes things pretty difficult.
I like Sonic a lot, for a variety of reasons, so I'm not planning to drop my service or anything like that. Heck, that EFF report alone probably guaranteed you a customer for life. That being said, I'd really like to know if there were any solutions (or better yet, expansion plans) for people in my neck of the woods.
