I've searched high and low and found nothing: Periodically the recording exercises take a really long time for my recording to "upload". So meaning I listen (this is fast), it prompts me, I record, I hit to finish recording. Then it sits there. It allows me to record again but it most of the time still hangs. This makes timed exercises useless and regular exercises a frustrating as I sometimes wait a few minutes for the server to respond. I've tried different browsers, same problem. I'm on broadband and checked my bandwidth when this happens, no problems.

I can turn the recording exercises off but feels like I'm missing out on a useful feature.

This doesn't always happen. Maybe 10% of the time.

Is this a known problem? Are the duolingo servers overloaded?
