JT, Try setting the AutoUpdateServerList to true for one session which should update the server list. Then you can change it back to false if you wish. Doing this every so often keeps your list current. I also find that I constantly get hooked up to Santa Clara and Jersey, neither of which work well for me. If those servers are supposed to be the best for me the trace route statistics sure don't support the premiss. I don't like any servers that have exodus.net in the routing, as often that's where my data packets stall. A few months ago a quote.com rep told me that exodus was having trouble with connections to UUnet. Taking those servers off my list helped increase the reliability of the program considerably. Those who don't use the UUnet backbone don't experience this problem. I wouldn't change the AutoUpdateServerList to false unless you often get connected to a problem server. Esteban

jtsaratoga asks: "We have seen quite a lot data discrepencies among different servers these days. Do you have reliable mechinism in place to sync them at least once a day and over the weekend? If you need to make some servers running in night session, have you thought about bringing half of them off line to do the necessary maintenance and alternate them every other night?" This is exactly what we do, but you have to realize too that we have very large databases that have to be copied around to all the servers in two different farms located at opposite ends of the continent. This mostly happens on weekend during our maintenance windows when nothing is trading, but we have restored servers overnight as well. It would be impossible to do this every night for all servers, or even half of them. We thought we had that 7/30 volume spike licked, but it was a nasty one and one of the offline development servers didn't get fixed - when we got into a bit of a crunch we had to put that server into production and that re-introduced the spike to some users. Our attempts to fix that one have inadvertently caused some of the outages you may have experienced. Yes - we can take servers out of production, but when there are hundreds or thousands of clients connected to it during the trading day we are reluctant to do so willy nilly because the users would be disconnected from service, and all those users would pound on another server all at once. But we can and do do this when absolutely neccesary. -- Gibbons
