Something is up with my VPS (virtual private server) the last 24 hours. I've twice had memory spikes that caused a kernel panic, which basically flat lined my system.
I did find out I was using an outdated Linode kernel, so hoping this might have led to the problem. Otherwise, I'll have to indulge in some detective work.
I run my own email server, too, so if perchance you sent me an email in the last 24 hours, you're not a spammer, and you're expecting an answer, you might want to re-send. I shouldn't be losing any email, but life is funny that way.
And if you see my site down, no worries: I've not packed up my marbles and run away from the web. I'm just dealing with some technical issues.
