Up until this morning, I had a website running on ec2 (freeBSD, ami-8cce3fe5, running django/uwsgi/nginx), with an elastic ip of 18.104.22.168 . The site was being served, and I could ssh into the instance. Now the site is down and I can't even ssh into the instance.
As I hadn't made any changes while I was asleep, I thought maybe the instance had just crashed, so I restarted it, but to no avail:
when i try to ssh into it, the request just times out. pinging the ip also times out. pointing a browser to it's public dns (ec2-50-19-97-56.compute-1.amazonaws.com) also times out.
Although I haven't messed with security groups at all, these are the TCP ports for reference:
0 - 65535 sg-3ab01353 (default) 22 (SSH) 0.0.0.0/0 80 (HTTP) 0.0.0.0/0 5080 0.0.0.0/0
Also, the system log that I can get from the amazon dashboard does not seem to contain any error messages. (the last entry is "Starting background file system checks in 60 seconds. Sat Jul 2 14:49:18 UTC 2011")
