::skyglyph have users in different regions.
In some cases, upload or download speed is low for a big set of photos and/or maps.
We are working on making our service better.
If you think your speed is low - run test at speedtest.skyglyph.com and send a screenshot to us.
Also, it will help us a lot, if you send the result of "tracert" command to us too.
We'll try to fix the problem.
