In Pictures: The worst Cloud outages of 2013 (so far)

From Amazon to Dropbox and Microsoft to Google, we've seen some nasty Cloud outages in the first half of the year. Which company failed the worst?

The CloudFare outage aftermath Fallout: For about an hour, if you tried to get to any CloudFare-connected site, all you'd get was a cryptic "No Route to Host" error message along with a mildly amusing sense of irony.

Fix: In a postmortem of the incident, CloudFare said a systemwide failure of edge routers -- which connect CloudFare's system to the rest of the Internet -- was the cause of the crash. While a few routers going down would typically cause traffic to be shifted, in this case, a bug took every single router offline at the same time.

Engineers found the offending code, cleared it out, then had to wait for teams in 23 data centers across 14 different countries to physically reboot all the routers.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
