Google Cache server is extremely slow

[PSGameDude33]

The cache server is from Level3. The ISP configured it so all the IPs that are from Level3 Google Cache (103.15.42.x) go up to 15mbps speed. It works fine for YouTube videos. But anything else I use from Google goes up to like 200 kbps speed.

For example downloading a Nexus image from dl.google.com (which resolved to Google Cache) is giving horrendous speed:

I can confirm the speed isn't limited to youtube videos as the Level3 speedtest server is on 103.15.42.x range and I get 15mbps from it.

Contact your ISP.

Contact your ISP.

How can they help? It's a problem with Level3 not the ISP
