Some of the players who I've seen struggling are in US time zones and have been struggling because they've been at work all day. I've seen more than one instance of players who signed up not being on until night time, even in their time zone. So, no, not everyone has been active for the event at reasonable hours. It would have been helpful to have a more specific time frame for availability, but no matter what time zone you're in, it's not a good idea to sign up for a time-sensitive event if you can only be around for a few hours during the night.
