Lambda the Ultimate

I recently have major problem with accessing the site. Posting comments fails randomly with no data, some request returns no data at all. Reloading page fails 1/3 of time. And so on.

This happen in different browsers and with and without VPN, so I'm quite sure that the problem is on LtU server side. The problem happens whether I logged in or not. The problem started to happen relatively recently. Few month ago everything was ok.

Does anyone else have such problems?

I suspect there is a problem is with hosting provider, or some "optimization" is involved like turning off VM when there is a little traffic.
