Is the site getting buggy?

Is anyone else having constant log-in issues? I have to log in every time I enter the site, but then I have to constantly log in over and over. If I click a different thread or read/send a PM, I have to log in. If I go to a different page I have to log in. So far this morning I must have logged in a dozen times. And all this despite clicking the keep-me-logged-in button every time.

I do use a VPN, is this possibly the problem or ??
