Check the ping through your route by using the pathping command on the cmdos or a program like PingPlotter.
Windows Search tool type: cmd
On the command prompt type: pathping -w 500 -q 100 -4 64.25.39.1
Wait for statics, usually takes 3 to 9 minutes.
Check out the hops for the latency and possible package loss.
If there is a problem on your route, it will show on the pathping. If the problem is on the first hops, it is on your ISP side; in case of mid it is a route problem and it is very unlikely you will get support for it but can still try to contact your ISP for a possible re-route; and if it is the last hops the issue might be on Anet’s side.
If there is no indication of latency issues, you might want to keep testing to make sure the problem isn’t there and if still don’t find any evidence, contact support to help you.
You can also paste the pathping log here if want us to check it out for you.
Good luck!
