Another "Glitch"?

Odd...

...I am presently logged in; I generally am always logged in (because I forget to log out, and I'm on here often enough that I just don't usually bother to log out)...yet, under the "online users" column, my handle disappeared moments ago. Now, as I type this post, my handle is returned to that column...

Of course, this may or may not have any bearing whatsoever to the strange behaviors which have been occurring on DP in the past 24 hours. Still...given the events of the past day, it seems prudent to at least mention this. Anyone else noticing their handle disappearing/reappearing in the sidebar? Is this part of the, er, bizarre incidents we've been experiencing here?
