Hello,
Our hosting provider, OSUOSL, will be performing some maintenance on the infrastructure that powers www.phpbb.com and several subdomains of phpbb.com.
During the following timeframes our sites might be temporarily unavailable:
April 19th:
9:00AM - 13:00 AM PDT (16:00 - 20:00 UTC). During this window we do not expect downtime.
April 20th:
10:00AM - 13:00 AM PDT (17:00 - 20:00 UTC). During this window we expect a 20 minute downtime.
This downtime applies to our various sites, including, but not limited to:
https://www.phpbb.com
https://area51.phpbb.com
This downtime will not affect any other installation of the phpBB software other than www.phpbb.com. However, the version check in your administration control panel might give a temporary error message.
Many thanks,
The phpBB Team
