I can confirm your reading from my own Wavoka and the cache servers that are giving trouble are under the control of Sabre who was with the pie team, so there is nothing that can be done on this side of the fence.
I have spoken to a pie team member and they have been told it is being looked into.
===========================
Glad I could contribute. I'm a program user and not very technical. I hope this settles out soon. WinMx will run fine for hours if I do not mess with it by responding to messages or use other features. I have put a notice in my hotlist auto responder that I am not using that feature until this clears up. Also included the URL for this site and message to check here for information about the problem.
