Hi kvm,

how are you doing the test, from a browser in the instance? which one to perform the same.
I also had some strange response when firstly installed Zorro on a Ohio zone. Now i have the two instances in Frankfurt and it works much much better, no problem at all actually.

By the way, no communication errors since the small incidents last week. The two Zorros in the two different instances are working without interruption.
I put weekend to 3+4 and got no problems at the weekend either.
