Editor's note: Check CNET News' separate story for details about what caused the outage for Google and others.
Many people found Google's search site was extremely slow or inaccessible Thursday, and other reports pointed to troubles with other properties including YouTube, Gmail, Google Analytics, Google Maps, Google Docs, AdSense, and Blogger.
Judging by a Twitter search for #googlefail, the problem was international in scope, though it wasn't immediately clear how universal the problems were. Google didn't immediately comment for this story, though it did confirm an earlier Google News outage that lasted about three and a half hours.
Google is central to the online lives--and livelihood--of many, and an outage shows exactly how central it's become--and not just through its primary business, search.
"The Internet dies without Google. Can't get to my bank Web site because it's waiting on 'google-analytics.com.' This is made of lame," said Twitter user Tadiera.

Google representatives have still not returned calls and e-mails requesting comment on exactly what happened this morning. The company has confirmed, however, that Gmail suffered what it called "a problem with Google Mail affecting a small subset of users." Google said it hoped to update that status by 10 a.m. PDT.
Updated 9:40 a.m. PDT: Google released the following statement: "We're aware some users are having trouble accessing some Google services. We're looking into it, and we'll update everyone soon." Google also sounded the all-clear whistle for Gmail: "The problem with Google Mail should be resolved. We apologize for the inconvenience and thank you for your patience and continued support."
Meanwhile, outages have been reported to us all over the world, including California, Maryland, Massachusetts, Florida, New York, Washington, Illinois, Idaho, Indiana, Arizona, Oklahoma, New Jersey, North Carolina, Texas, the United Kingdom, Dominican Republic, and Malaysia.
Keynote's Internet Health report is showing some interesting data this morning as well. Two network routes involving NTT, a Japanese telecommunications giant, are showing significant packet loss on connections to Qwest and Verizon. We're trying to get more information and an explanation from Keynote representatives.
Updated 12:25 p.m. PDT: Google gave a brief explanation of the problem on its main blog:
Imagine if you were trying to fly from New York to San Francisco, but your plane was routed through an airport in Asia. And a bunch of other planes were sent that way too, so your flight was backed up and your journey took much longer than expected. That's basically what happened to some of our users today for about an hour, starting at 7:48 am Pacific time.
An error in one of our systems caused us to direct some of our web traffic through Asia, which created a traffic jam. As a result, about 14% of our users experienced slow services or even interruptions. We've been working hard to make our services ultrafast and "always on," so it's especially embarrassing when a glitch like this one happens. We're very sorry that it happened, and you can be sure that we'll be working even harder to make sure that a similar problem won't happen again. All planes are back on schedule now.
