It is not known what has happened, they have not given exact information.
But I have been told that soon the school will be back, maybe for December.
Another page also had problems, a friend told me that the winamax page was hacked for 5 days, I don't know if it will be the same pokerstars problem
Kind of strange for such a big company to not bring back the school for so long. Was always nice for promos and strategy. Unfortunately stars is no more what it once was, also they are cutting in customer service lately.
It is a strange situation. When the problem happened in august it started with invalid ssl certificate which expired. Big company like stars will not allow certificate to just expire without renewing it if they plan to keep the school. I personally expected announcement that school will be closed soon after this. Now they announced expected return at end of october which also did not happen. They are either trying to reorganize it totally or they have just not decided what to do yet. Will see.
I entered a few days ago and even to got a school ticket is a big process, you need to watch some online videos in realtime and then the organizer tells you how to reclaim your ticket and its all confusion, maybe I will wait until things return to normality, but it is a shame
