Twitter Leads Social Networks In Downtime

illectro writes "A study on site availability by monitoring service Pingdom shows that in 2008 Twitter greeted users with the 'Fail Whale' for more than 84 hours, almost twice as much as any other site. At the other end of the scale imeem and Xanga managed less than 4 hours of downtime for 99.95% uptime. Myspace, Facebook and Classmates.com were the only other sites studied which managed to stay up more than 99.9% of the time."

84 hours????

And yet it had 0% impact on my life. So who really cares.

Does it make that much difference?

If Twitter was the worst, with 84 hours downtime, one year is 8765.81277 hours, which means that Twitter was down .958268243% of the time. Not .9 (90%), but .009 (nine tenths of one percent). IOW, it has an uptime of 99.05%. Sure, that's not great compared to 99.95%, but it was down less than 1 in every 100 times you tried to reach it. I'm pretty sure Yahoo! doesn't manage that, and I know Microsoft's download servers don't manage that...

Good numerical point, but Yahoo hasn't failed to load for me any time in the last 10 years, with something like 10-50 page views per day. Their uptime is thus no worse than based 0.99997 on my experience, which is means 300x less downtime than twitter.
