This three-week uptime survey of 11 social bookmarking sites shows 100% uptime for Digg, Fark, Slashdot and Netscape. Other sites are less fortunate.

Digg and Del.icio.us are at the forefront of social media and web 2.0, but they are far from alone. They have plenty of competing services, and these social bookmarking sites are getting a lot of traffic. So much traffic, in fact, that some of them seem to be having website problems.

Downtime of 11 popular social bookmarking sites

This is the total downtime since May 3 for each of the 11 websites in the survey.

Website			Downtime
Digg.com		     0m
Fark.com		     0m
Reddit.com		 1h 28m
Netscape.com		     0m
Slashdot.org		     0m
StumbleUpon.com		    33m
Del.icio.us		     5m
Blinklist.com		20h 11m
Newsvine.com		 2h  6m
Furl.net		 4h 28m
Meneame.net		    24m

As you can see, Digg, Fark, Netscape and Slashdot have all had perfect uptime records so far, and Del.icio.us isn’t far behind with just 5 minutes of downtime.

Blinklist, on the other hand, has had more than 20 hours of website downtime in just these three weeks. The longest individual downtime for the Blinklist website was 4 hours and 46 minutes.

One possible explanation to all this downtime could be that Blinklist is having scaling issues (a.k.a. growing pains). Sometimes there is a back side to being popular.

Unless you’ve been hiding under a rock lately, you’ll know that last week Apple announced the iPad, its new tablet device. Reactions have been a mixed bag, and a storm of discussion has swept through the blogosphere about various features the iPad should or shouldn’t have had.

One of the main complaints so far has been the iPad’s lack of multitasking. (To be precise, multitasking is a bit of a misnomer here; the iPhone OS has multitasking. What people really mean is only allowing one app at a time to run.)
