How Google Routes Around Outages 105

1sockchuck writes "Making changes to Google's search infrastructure is akin to 'changing the tires on a car while you're going at 60 down the freeway,' according to Urs Holzle, who oversees the company's massive data center operations. In a Q-and-A with Data Center Knowledge, Holzle discusses Google's infrastructure, how it has engineered its system to route around hardware failures, and how it responds when something goes awry. These updates usually go unnoticed, but during system maintenance last month a software bug triggered an outage for Gmail."

This is an alarming development because it's both difficult to detect (software running on your PC can't detect it) and significantly more useful to the botnet operator than infected PCs because home routers generally run 24 hours a day, unmonitored. The botnet malware contains the shellcode for over 30 different Linksys models, 10 Netgear models, and a variety of other cable and DSL modems (15 different shellcodes). Any router that uses a MIPS processor and runs the Linux Mipsel operating system (a port of Debian for MIPS Processors) is vulnerable if they have the router administration interface, or sshd/telnetd in a DMZ, with weak username/passwords. DroneBL noted this includes devices flashed with the open-source firmwares openwrt and dd-wrt."

The State of UK Broadband — Not So Fast 279

Posted by kdawson on Wednesday November 26, 2008 @06:29AM from the but-you-have-actual-competition dept.

Barence writes "The deplorable speed of British broadband connections has been revealed in the latest figures from the Office of National Statistics, which show that 42.3% of broadband connections are slower than 2Mb/sec. More worryingly, the ONS statistics are based on the connection's headline speed, not actual throughput, which means that many more British broadband connections are effectively below the 2Mb/sec barrier. Better still, a separate report issued yesterday by Ofcom revealed that the majority of broadband users had no idea about the speed of their connection anyway."
