Toss this into a cronjob and the website will never die ;)

Outlive an AWS account that never generates a bill? That could be a challenge.
Maybe run something like this hourly, which would give about 2 hours notice:
curl https://www.thiswebsitewillselfdestruct.com/api/get_ttl -s | wc -c | grep -v 26
(Though don't run it right on the hour as too many people doing that might temporarily take down the website.)
