It's clearly not an overloading issue. If the outage was a couple of hours sure, maybe it's a load issue. But it's after noon on the following day and the system is still broken.

Plus, it doesn't make sense that it would be overloaded. They should have known exactly how much load to expect based on the number of caucuses held across the state. Also, Iowa isn't a populous state so the total number of datapoints is not going to be all that big. This should not have been a hard problem. The DNC is looking like a bunch of idiots this morning.

Perhaps the statement was referring to the telephone hotline, used as a backup means of reporting results, which was apparently overloaded with calls.

The statement was about people waiting for hours for the app to respond when they tried to upload the results, and some giving up and going to bed after it failed repeatedly.

Yep, the phone line was apparently overloaded, but that still doesn't answer the question of what happened with the app?
