I am from Slovenia, European Union, my ISP is T-2.
I've noticed slow loading for quite a few of websites, and the culprit seems to be fonts.googleapis.com. It appears to be routed to China instead of something closer. If I click on Query Log's entry for a request details for this domain, the Country field displays China.
The other day it seemed the issue went away (i.e. googleapis IP was again just a few nodes away), but it's back again, slowing down display of most websites (those which use googleapis or other Google services).
Traceroute to your servers is just fine. The issue is related to those which are (I suppose) dynamically routed as per users' location. So for some reason, Google's are now again routed to China.
Please check ID 790599 for traceroutes.
