Mosso Powers Popular Site for 2008 US Presidential Race : Rackspace's Cloud Computing Division Helps Political Sites Scale to Meet Traffic Spikes w

SAN ANTONIO (Business Wire EON) September 30, 2008 -- In January 2008, information was posted about the presidential debates on YouDecide2008.com, resulting in an increase from 25,000 visitors to more than 300,000 ? in one day. When a shared hosting provider was not able to scale to support the spike and the site crashed, the site was migrated to Mosso's The Hosting Cloud.

"Since making the switch, Mosso has helped YouDecide2008.com stay up and running with usage numbers spiking more than 600 percent during pivotal points of this year's election," said Nathan Ashworth, YouDecide2008.com founder. "They've given us the freedom to grow and not be punished by our own success. Additionally, their customer service has been phenomenal ? it really feels like our business matters to them."

YouDecide2008.com was created by political information junkie and IT industry professional Nathan Ashworth. Since 2006, he has been populating the site with commentary, speeches, surveys, video, general information and news from both the Republican and Democratic parties. YouDecide2008.com's growth demanded a solution that would scale seamlessly without compromising speed or end-user experience in any way. Mosso's The Hosting Cloud provides cost-effective clustered processing, load-balancing, and redundant storage specifically designed to support high performance sites subject to frequent and unexpected traffic surges.

Nathan's sentiments are echoed in a recently published review by Bitsource, a blog that promotes and evangelizes various trends, opinions, and practical use cases in the technology and enterprise computing community.

"Mosso's cloud scales extremely well and with absolutely no user intervention, which allows it to claim the title of a true cloud computing platform," said Matthew Sachs, systems administrator and owner of Bitsource.

"YouDecide2008.com shows exactly why Bitsource rated us so highly and why flexibility is needed in this sort of landscape. As this election year continues to unfold, there will be millions of people looking to the Internet for information?especially as we get closer to November 4th," said Jonathan Bryce, Mosso co-founder. "Our core strength is the ability to quickly scale and adapt to changing circumstances, including huge traffic surges as visitors hit these popular sites looking for up-to-the-minute information on the elections. It also explains why customers are counting on Mosso to host important sites such as those related to the presidential race."
