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????

[sunking2]

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

84 hours?!?!

[RoFLKOPTr]

I find it kind of strange that a site as incredibly simple as Twitter had so much downtime. Granted, they probably don't have the multiple dedicated redundant datacenters to their name like MySpace and Facebook do... but still, they're only serving little tidbits of text.

Go outside, take a sunbath, twitter your friend about it... err, ha, well...

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.

and here I am...

And here I am worrying about whether I should see my doctor after 4 hours of uptime.

Twitter doesn't work by design

[itsme1234]

I think many of us recognize the potential power of twitter-like thingies. With this in mind I recently joined. It is beyond disappointing.

- the site itself is barren, with basically no features - it is just like a '98 site in a bad way (not in a "Google-like" minimalist way)
- can't get updates by SMS in Europe. OK, fair game, it isn't free. But you should be able to at least post by SMS, right? Somehow although they do offer local numbers (very nice) I wasn't able to actually verify any phone so can't update by SMS
- they had updates by Instant Messenger as official feature for a while but couldn't make it work (why?! at least it should be practically free for them unlike SMS)
- there are some 3rd party solutions to update by IM but none work (plus you have to trust the 3rd party)
- same as above for updates by email

So, yes, nice idea but poor execution.

Twitter Developer Alex Payne on Rails performance

[dandv]

In an interview with RadicalBehavior.com, Twitter lead developer Alex Payne commented:

By various metrics Twitter is the biggest Rails site on the net right now. Running on Rails has forced us to deal with scaling issues - issues that any growing site eventually contends with - far sooner than I think we would on another framework. [...] At this point in time there's no facility in Rails to talk to more than one database at a time. [...] All the convenience methods and syntactical sugar that makes Rails such a pleasure for coders ends up being absolutely punishing, performance-wise. Once you hit a certain threshold of traffic, either you need to strip out all the costly neat stuff that Rails does for you (RJS, ActiveRecord, ActiveSupport, etc.) or move the slow parts of your application out of Rails, or both. It's also worth mentioning that there shouldn't be doubt in anybody's mind at this point that Ruby itself is slow. [...] I think it's worth being frank that this isn't one of those relativistic language issues. Ruby is slow.

Twitter's downtime

[teknognome]

While I don't use twitter, it's downtime is bad enough (or people are obsessed enough) that not only is there IsTwitterDown.com but also IsIsTwitterDownDown.com

CRUD-style applications

I think that says it all, right there.
