I wrote a new script to help me manage DNS on the server. Apparently I didn't test it enough, and it borked DNS a few hours ago, making the server unreachable for a good chunk of people. I've fixed it, but the TTL is 3600 seconds, so most of you aren't gonna see this for at least another hour or so. I'm just posting this to let you know why the outage occurred. Totally my fault. Sorry!
