Blogger was not always known for a stellar uptime record. In late 2006, the service practically had to write "a novel" about continued outages. In fall of 2007, I railed against Google for ignoring users during another major outage. But services mature and times change.
Royal Pingdom's Downtime Report. Blogger Scores a Zero.
With the backdrop of Tumblr's highly-publicized downtime of more than a day earlier this month, Royal Pingdom also spotted occasional outages at WordPress, TypePad and Posterous, each of whom looked great compared to Tumblr's unfortunate blip, but not as spotless as the often overlooked Blogger.
Getting Slashdot, Scoble and Spiegel Bumps Simultaneously
While escaping system-wide downtime is a major win in itself, that doesn't speak to the services' ability to scale under pressure. Gruber recommends the WP Super Cache Plugin for WordPress, letting users serve more than a page a second, as it's self-hosted WordPress blogs that often get crushed with one of his links. But I've been linked from Daring Fireball a few times and lived to tell the tale. Same for Slashdot, Techmeme, Hacker News and the Huffington Post, all of which are capable of sending solid and sustained traffic on good days.
Techmeme, Hacker News and Scoble Don't Bring Down Blog
Similar to how Google is well known for its Web site never going down, I have to assume Blogger has mastered Google's distributed architecture, and makes no single blog, or its hotspotting, an instrument for failure. This blog didn't slow or go down when tens of thousands of visitors dropped by this July to tell me I was an idiot for switching from iPhone to Android. It also didn't go down when I questioned the usefulness of Google Wave last year, or when the Huffington Post liked my recap of David Kirkpatrick's Facebook Effect.
Not Even Daring Fireball Could Take the Blog Down
Even the largest services have occasional downtime. Facebook was down last week, intentionally, due to a code push ahead of schedule. Twitter has had its share of bumps, though the site has gotten much better in the last year, and even Facebook subsidiary FriendFeed went down this weekend. But Blogger users are sitting pretty knowing their blogs are going to be up and responsive, even under pressure.
