Does anyone see value in putting a open exchange point in one federal in Springfield, MA?
Springfield, Mass.? Can't hurt…
Agreed. There's essentially no reason not to put in an exchange, anywhere three or more ISPs are present.
There's also Boston Internet Exchange which has been slowly picking up steam, over at 1 Summer; you may want to look into remote interconnection.
That's 90 miles away, so I'd recommend not trying to extend their switch fabric that far. If you were considering a second exchange in Boston, I'd definitely recommend using the same switch fabric for both locations, but not at 90 miles of remove. That would put a pretty big burden on the smaller ISPs that are likely to be participating in Springfield. -Bill
