hi,
the information about maintenance was published on 06 October 2013. i'm using server 5 with load 49% (now), but tv still has a very heavy hickup. there is no problem when lag is up to 350ms but now very often it is over 2000ms. apart from this there are a lot of "server down" periods, several every day that last form 30 seconds to a few minutes.
all configs was downloaded from here, and before this your service was flawless.
best regards.
Lukasz
