Update at 6:15 p.m. PDT to add areas that may likely see delays in delivery.

Update at 7:55 p.m. to reflect that the site has since come back online.

Netflix customers expecting a little red package soon may be disappointed.

The largest online video-rental service has suffered a technical glitch that has knocked out its Web site as well as its logistics and delivery systems, according to a Steve Swasey, a company spokesman.

The malfunction, the source of which the company won't reveal, began at about 7 a.m. PDT. The site came back online about 12 hours later, but the malfunction caused Netflix to miss the deadline to mail a large number of shipments scheduled to go out on Monday--affecting customers across the United States, according to Swasey. "We did send some shipments, but most of them will go out on Tuesday."

Swasey declined to specify what percentage of the company's more than 7.5 million customers would be affected.

The blackout was the second longest in company history. In July, Netflix suffered an outage that lasted longer than 18 hours. On that day, the company's shares fell 7 percent as the market punished Netflix for a drop in customers.

This time, the glitch came as Netflix's customer numbers are on the rise and its stock is soaring. Stock analysts upgraded Netflix on Monday, and the company closed trading at $38.18, up 5 percent. Over the past six months, the company's shares have doubled in value.

One of the differences between the two outages is that Netflix's logistics and shipping systems were not affected in July. With the more recent glitch, Netflix continued to ship DVDs but that changed sometime Monday afternoon.

In a message posted to its site, Netflix told customers not to worry because the company's "distribution centers are still sending and receiving DVDs." A check of the site's HTML source showed that the company rendered that sentence invisible sometime later.

"Our engineers have been feverishly working on repairing the problem all morning," Swasey said. "It was an unanticipated, unplanned outage, and we apologize to our customers."

Site outages are typically not a big deal, and any company can suffer one. But a blackout that lasts for more than an hour is rare, and one spanning several hours is rarer still.

Netflix, which has 7 million subscribers, said that customers needn't worry about their stored movie picks. None of their information will be lost.

There are just over 24 hours left until the formal announcement of Facebook's new advertising initiative. Is the site experiencing some jitters in preparation?

Late last week, one of my editors IMed me to ask whether Facebook was down. It was, but within five minutes, it was running again. Over the weekend, I noticed that the site was logging me out periodically. I wanted to check out a friend's new profile photo, but I repeatedly got log-in screens instead.

Then, on Monday morning, the site has slowed to a crawl. When I attempted to approve a new friend request, Firefox asked that I save a PHP file to my computer rather than actually opening up a page. Eventually, it allowed me to approve the request, but I'm still getting "page timed out" messages on occasion.

It's not necessarily anything major: in the summer of 2006, both Craigslist and MySpace.com experienced major outages that threw off the sites' operations, for example. And don't even get me started on Second Life. But the Facebook mini-outages and glitches have been noticeable, and that's not good when you're trying to get big ad partners onboard a new project.

There's no official word from Facebook on whether all this is due to server issues, connection issues, or the fact that I used a stupid profile photo of myself in my Halloween costume. (I've since taken it down.)

Has anyone else out there experienced Facebook instability over the past few days?
