By way of explanation as to why some people might get the error andothers will not.

When you log on to Blackboard 6, one of the cookies that is set is "BB6ProdBigIP". This identifies which backend application server your session goes against. It has an 8-hour expiration, so once it is set, you will typically continue to go against that application server.

Others (even the person at the next computer) may be going against another server and keep going against that server. If one server is having a problem, it will only show up if your session is tied to that problem server via the cookie.

If you delete the cookie, you might be reassigned back to the same server, but with luck you might be assigned to a working server.

We are working on addressing this issue so that our load balancer ismore intelligent about detecting internal server errors and will re-assign people automatically when they occur.

Thanks

David
