They did some tweaking on their side, but the iperf numbers have only improved to 360Kbps. Our backup link on the other hand dropped to about 140kbps...but the thing is, we're paying close to US$ 1k for the new link; our backup link doesn't even cost half that amount. For now we're doing the standard HTTP/FTP download tests, just to verify the iperf numbers....but it's not looking good, at least for our ISP...
