Seems like Twitter is having a bad day with multiple slowdowns and timeouts over the last 24 hours as can be seen on the following charts.. (all times are GMT)
Twitter Uptime (last 24 hours):
Twitter Response Time (last 24 hours):
As you can see the down periods correspond with spikes in response times meaning the page fetch timed out when we checked it – we have a default 5 second timeout for http tests and when a page (html only) takes over 5 secs to download its not generally a good thing. As a result and at the time of writing this blog post their uptime for the last hour is down to 89.86% and 97.19% for the day which for a system as popular as Twitter is sure to annoy many. In fact a quick search shows many complaining tweets already and it’s only a matter of time before they get raked over the coals again by Techcrunch! 
Compare that with the last month and you will see that its usually much better even though they do still have the occasional dip in performance..
Twitter Uptime (last month):
Twitter Response Time (last month):
In fact twitter uptime over the last month has been a fairly respectable 99.76% and for the year so far it is 99.85% so not too shabby overall and the infamous fail whale has not had as many opportunities to show itself recently as it did last year!

** UPDATE: its been a couple of hours since I first posted this and there is clearly an ongoing performance issue at twitter today – the last few hours have been significantly slower than usual and in fact the average response time for today has reached 1211ms. Compare that to the time for the year so far which is only 633ms, for the last month 850ms and last week 898ms, so its quite a change and in fact appears to be trending towards increased slowness in general. So what is going on at Twitter HQ today? Is it the increased visibility of the search link resulting in their servers getting hammered? Or is there some event going on now causing a big increase in tweets?
