Thanks

The more tests the better!
As a start, a traceroute/ MTR and a few pings to affected sites are always helpful. If it's Akamai related, you can ping whoami.akamai.com.
For other stranger issues, wireshark is where it's at
So I have been trying to do a Tracert the whole evening as the issue is back again like clockwork. And I like to think I am fairly clued up with what I am doing and the Tracert its not hopping very far... anywho I have PMd you the complete Tracert and the ODD ones.
But like clockwork at 8pm it slowed to a crawl for certain services.
