Website is blank

Tried to load my website a minute ago and… it’s a blank page. So I peeked from the command line (name and IP changed to protect the innocent):

[mysite][~]$ wget mysite.com/index.php
–16:59:22– https://mysite.com/index.php
=> `index.php.1′
Resolving mysite.com… 192.168.1.1
Connecting to mysite.com|192.168.1.1|:80… connected.
HTTP request sent, awaiting response… No data received.
Retrying.

–16:59:22– https://mysite.com/index.php
(try: 2) => `index.php.1′

I had a peek at MySQL (connected via the command line) and was able to connect and most of my data was there (looks like the most recent post is gone, which makes me wonder if there was some sort of shenanigans with my hosting provider).

I’m not sure what version of WP I’m running; don’t know where it would be in the WP files. I know it’s old, though – last time I upgraded was in January of 2007 (yes, yes I know). I want to say it’s 2.3.1 or thereabouts.

Any other suggestions as to how I can debug the problem? I can connect to the database and my stuff *looks* like it’s there, so I’m sorta at a loss as to what to check after that.
