Why has the server been offline for about an hour?

i know this is kinda a dumb question but i just wanna know why it has been offline since like, 5pm est. It is 6:06 atm. Im sure it will be online soon but i have no clue i havent been on in a while

ok i just tried again and it said server is on lockdown, what is that?

Sorry about that. Everything is working again.
