Dallas servers are all switched out to a different host.
I put 10 new servers online in Dallas tonight. This will better parallelize tests. Basically when you test... there's an even better chance that you're testing on a server all by yourself.
Also relocated DE and added a 2nd DE server, again to help parallelize.
I see better results on both.
Dallas for instance...
TestMy.net Test ID : a_jeL_PBv
I was consistently below 200 Mbps before on the same test. I see improvement, I hope you do too.
