Fios should already be available in Dorchester, MA 02125. There are many multiple family homes which means there will be many potential customers without having to spend a ton of money running cables like you may have to in more rural areas. My friend in Holbrook, MA 02343 has fios and I don't see why that area would be offered fios before the more densely populated areas. I don't want to have to support comcast because I had bad expiriences with them in the past but they are the only ones who offer good interent in my area. The 3.1-7mbs down just is not good enough to stream content to and from sites like twitch.tv.
