Hi Psytech,
in the moment we are not able to handle events on Saturday due to private things on weekend. So it´s not safe that there would be an admin to manage the servers on saturdays. As I know from my admin mate, Sunday ist not much better.
We also see that the Friday is maybe not ideal and we are also thinking about to change it, but without a solution now. For now we stick to fridays, but if we want to change it, we sure start a poll to look what´s the best.
Greetings
