The loading speed of the AirMo is slow. The video playback is really slow as well (i.e. waiting the circling for seconds, and then playback for less than half a second, and then waiting the circling again and again).

I encountered the same issue here.
Looks like the cdn doesn't work well.
I took 938 seconds to complete loading one single airmo page. (url: https://air.mozilla.org/monthly-speaker-series-metadata-with-harlo-holmes-2016-10-12/) "

During that delay, I pinged air.cdn.mozilla.net, which seems to be where the file is located according the network monitor on Firefox, I got average ping time around 45ms.

Linears-MacBook-Pro-3:~ linear$ ping air.cdn.mozilla.net

It looks reasonable to me to a cloudfront Japan node, though I don't know why it directed us to Japan node while there actually has nodes at Taipei."

Here's the thing about this problem:

 - Is the problem with your ISP connection in Taipei?  Like, is all connectivity 
   to systems outside the office slow and problematic?  

or

 - Is it that the content from CloudFront is the problem?

If it is the latter of these two, and I believe it is, then this is a problem with AWS, 
and not something Netops can control.

I'm going to close this bug.  We're looking at new carriers but  I expect latency to continue to be troublesome due to the overall distance.  Any issues
