Transact has had disconnect problems off and on for the past 2 weeks (some days no problem, other days several disconnects in one day). Before this period, I had not had a problem with their data feed for many months.
In talking with them today, they said that they are implementing changes to their servers tonight and over the next couple of nights to solve this connection problem.
I hope this solves their problems, because other than these recent problems, I've been quite pleased with their performance and pricing.
