Ask HN: Best host for static HTML microsites?

So I know my way around web development, and I have a meticulously crafted lighttpd.conf running on a few tiny VPSes.

Problem: stuff goes down occasionally, severs require a reboot, and while it's great for hardcore wordpress optimization (which I do on my main blog), I've increasingly found myself modifying my powerful lighttpd.conf script to add yet another 3-page static html microsite.

Can anyone recommend a cheap, painless way to host a bunch of low-traffic static HTML across a dozen or so domains?

* Zero-configuration deployment of new sites. It would be great if I could just put some files in a folder called "example.com" and do a git push.

* Configurable subdomain support. S3 won't cut it.

* Reliable / no waking up to do a reboot at 3am

* Cheap: same cost or less as what I'm paying now for the VPS.
