I would very much appreciate anyone sharing their experience relating to connectivity issues they have had - looking for 24/5 trading.
Definitely get connections from two different providers and make sure they are as physically different as possible (i.e. don't get connections from people that are co-located at the same CO if you can help it). Personally, I trade from my home, and have Charter cable and Verizon DSL. Coincidentally, Charter is down this morning, as it is about once a month for a few hours (better than a lot of systems, from what I hear), making me feel good about paying extra for that DSL line.
