No one is sure what is going on in any detail. But, we have seen the group chat for the Mad Pea Blood Letters’ hints (Madpeas) go down a couple of times and the Firestorm Support group. Both groups have been able to send notices to their group’s users advising them of the problem.
The restarts for hardware updates may have been contributing to the problem. No changes are being rolled to the chat servers this week because of the hardware update restarts. Whatever changes are being made to day ARE affecting group chat.
The Madpeas group chat was down late yesterday (11/18). It is still down now (11/19) 3± PM SLT.The Firestorm group is back up now.
