what is wrong with this

It sounds more like your inability to run a website correctly. Don't blame your host when it's you that lacks the ability to configure and manage your site. Running your site isn't their job. It's yours.

Amerinoc works fine for me today, and yesterday, and all of this and last year.

Some of sites might not work, but as Babaganoosh pointed out - not really the hosts problem ;)

all mine are up and running fine

mines are up and fine.
thumbnails not showing up, without further details, hardly seems a hosting problem.

Mine are all ok, just like they were yesterday, day before that, last week, month before that and so on. Rock solid guys! Maybe you need to go over your html or php code once again?

My sites are up.
