Hi Pat!
There seems to be an issue with the Frankfurt node. Pls have a look at the CPU load for the same site, same time between Frankfurt and Paris.
As you can see, this effects heavily the measurement results:

The site is physcally hosted in Frankfurt, so the Frankfurt node should actually be slightly faster. But due to the CPU load issue, it appears to be 50% slower.
Kind regards,
Markus
