Thanks for letting us know about the issues here, and sorry about these issues. We've taken a look at the system metrics on the Java servers and everything should be working as normal, with almost every program running in one second. There will be the occasional time where the program doesn't run, but just running again should fix that. In many instances where programs don't run there may be buggy student code causing an error (which is normal). If you are having delays on a particular problem or have had repeated delays in your classroom, you can email us at firstname.lastname@example.org and we will dive more into the problem.
