Had similar issues in the past and usually something on the path is broken. Anyway it's very slow right at the start, as can be seen from the tracert:
There is nothing wrong with that tracert.
Nothing wrong? I compared to another site; that had only 1 time out and then 6 steps all of 20ms.
Perhaps you could explain a little?
The only relevant part of a tracert is the response from the destination. If that is OK then the rest is immaterial.
