AngelFire

I don't know if this was mentioned, but this is probaly the most reliable free host you can find. I have a site I made 5 years ago and haven't even touched in 5 years which is still active on Angelfire. Though, you do hav eto put up with their ads and pop-ups...but you'll be on a host that may be more reliable than some paid hosts

Unfourtunately, I haven't tried them out too recently..and it looks like they have even more ads on the newly created accoutns..but..if you have an old account...nothign is ever added to your page..so, if before you only had one banner ad, that's all you ever get
