This was in the recent news:
Maintenance is complete and we would like to direct your attention to the alert regarding the technical update.
And this was in the BFH Forum:
It has come to our attention that some of you maybe getting our technical update confused with our maintenance. We would like to make it clear that today’s maintenance is only a preparation step for when we are ready to introduce the actual Game Update. We want to ensure that you, our community, get as smooth an experience as possible, both during and after the Update.
We would also like to notify you about the technical update that will be implemented soon. We’ve encountered a problem with some code provided by one of our partners. This code is part of the matchmaking system. We feel we must fix this issue before we can make the update available to you all. We’re in constant contact with our partner as they work through the problem.
We apologise for this unforeseen delay. However I’m sure you understand we want this to be fixed and tested properly, before we release it.
