"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

At 11:19AM I got "Not Found" for OMX, MAC, and a few other tickers, was connected to server. I've stopped/restarted IQ a couple of times until I finally got market data for these (and other) tickers, works fine since than on the very same server.

I've used the C++ Level1 Socket demo app. to ensure it's not a bug in our code (which produced the same not found errors), can PM the screenshots of the IQ Connection manager + the demo app if needed.

What could be these periodic "not found" errors be? At some point I got these "not founds" for 30 of the ~300 tickers I watched.

We had a brief problem at the 66.112.148.XXX server farm this morning causing various symbols starting with the letters K-P to be returned as invalid on some servers. This issue has been resolved and no more problems are expected.

Thanks for the prompt reply Steve, a few more questions:

1) would it be possible to post some kind of notification on this site in such a case stating that (in our case) 66.112.148.XXX servers may return invalid symbols, ETA for the resolution, than update once the problem is resolved? (If there's already such than could you please direct me there) Reason why I'm asking is that I've just spent 2 hours debugging our code as I initially thought it was a bug on my side, as such has error never happened before w/ IQFeed, next time I could save this time.

2) If say in the future I suspect that some servers are experiencing problems (say these 66.112.148.XXX servers), how could I force IQFeed not to connect to these or to connect to some specific servers. ie how to work-around once I suspect some servers are experiencing problems?

LVarga, there is not currently any method in place for notifications. I certainly understand your fustration with debugging code that isn't actually bugged. In the future, I would recommend using the example apps as a first point of testing data related issues. If the example applications do not work, then there is a good chance that your app isn't the problem. I would also recommend getting in touch with our support department (email, chat, etc) to find out if such problems are known.

It is possible to force your connection to a different server farm by modifying your windows hosts file however it is not recommended because this bypasses load balancing which could potentially cause problems in the future. Due to the way the servers are load balanced, simply reconnecting a few time should get you to a different server farm.

I'd like to see a function in the interface to IQConnect that lets you request 'go on to next server' so that one can get another server immediately and not have to futz around with connection / disconnection until a different one comes up. This stays with your load balancing and lets us check quickly to see if it is a server issue. I am astounded sometimes in how many times I have to re-connect to get a different server.

Also, I have a big difference here in both latency and hops between the two server farms - 156 gives me 13 hops and an average latency of 43 m-sec, 148 gives me 19 hops and 62 m-sec. I have lower errors associated with the fastest system.
