Pitch black darkness

Last night, the power went out everywhere. Completely. I happen to be staying in a village in the province of Dobrogea, Romania at the moment, and just as I stepped out of the house to walk to my car, all the lights blinked out of existence. It was, as they say, a dark and stormy night, with nary a star in the sky, not to speak of the moon, which had probably been stuffed in thick sackcloth and kidnapped.

Do you want to know what things look like when you’re in the middle of a wide open field and everything goes pitch black? It looks something like this.

Pitch Black Darkness

It’s an eerie feeling, one that throws you for a loop, even if only for a few moments. I looked around, but there was nothing to see. I reached about me, and wasn’t sure where to reach for a wall or something to hold on to. Everything was black. Even the dogs went quiet. Then, someone in a house nearby stumbled over something and mumbled some sort of swear, then called out for a light from his wife. Others, elsewhere, called out to each other. Things came back to life, but it was still pitch black outside.

I pulled out my little spotlight, the same one I reviewed recently, and found my way to the car. I unlocked it, and the interior lights came on. I climbed in, sat down and turned on the engine. The dashboard lights came on, reassuringly. Then I realized something which sounds obvious to someone who doesn’t have to deal with a power failure, but is a downright epiphany when you’re in pitch black darkness: cars have standalone electrical systems; they do not depend on the grid for power; they make their own power. When the grid goes down, your car can still run, thanks to its battery and to the fuel that makes its alternator turn and charge that same battery. It’s an amazing system when you think about it. I don’t know what we’d do without it.

Shouldn’t homes have similar standalone electrical systems, just in case grids go down? Sure, we’ve made inroads with solar panels and wind turbines, and some homes do have batteries that charge up from the sun or the wind, but the overwhelming majority of homes in this world don’t have any sort of backup power. If the electricity goes down, they’re down as well.

We should really invest more into making each of our homes more self-sufficient. Each home ought to be able to function, at least for a period of time — say 4-8 hours — without grid power, in and of itself, from power stored in batteries or capacitors or in some other container of energy, so that people can carry on with their lives and at least have enough time to prepare for a prolonged power outage once the grid power goes out.

Sorry about the growing pains

My sites were out of commission yesterday afternoon, evening, and part of the night as well. Each outage lasted anywhere from half an hour to a couple of hours, and drove home very clearly this message: I need a web server upgrade.

While it was certainly frustrating to see my sites go down, and to see that no matter how much I tuned Apache or MySQL, I couldn’t meet the traffic demands, it’s also encouraging to see that I first outgrew shared hosting plans, then outgrew a small dedicated server, and had to (now) upgrade to a more powerful dedicated server. My site stats show this same trend. Traffic levels have been growing steadily throughout this year and even more in the last few months. October in particular has been rough on my little web server.

Yesterday, Google and Yahoo had been indexing my sites, on top of the usual, fairly heavy traffic. I started having serious performance issues during the afternoon, which led to a small outage. Google got done with my sites after that, but Yahoo kept going, and Cuil, the new search engine on the block, joined the party as well. Cuil is known for taxing web servers heavily when it indexes sites, and it was merciless on me last night. It, together with Yahoo, brought my server down and kept it down for close to one and a half hours.

I got it back up and re-tuned Apache and MySQL with Chris Johnston‘s help, but at some point during the night, it went down hard, and stayed down. When I woke, I decided enough was enough. It was high time I upgraded.

Thanks to my awesome hosting company, SliceHost, I was able to double the specs of my previous server in less than two hours. Before non today, my little web server morphed into a larger, more powerful one that can handle the current traffic levels with ease. We’ll see how long it can keep up before I need to upgrade again. You can help there. I don’t mind at all if I have to upgrade again in the near future, should my traffic levels warrant it.

Thank you for sticking around!
