Cyber Monday 2011 - Web Performance Results

We monitored the web performance of the top 55 Internet Retailers website during Cyber Monday 2011.

With so much attention being paid to online revenue this shopping season we wanted to see how well all the major retailers handled the massive influx of shoppers.

We monitored the web performance of the top 55 Internet Retailers website (Excluding Netflix, Blockbuster, 1800 Flowers, Scholastic, and Redcats USA ) from our US Nodes using Internet Explorer 8 browser. The goal was to compare the performance of the sites and to see how well each website handled the traffic during the event.

One interesting development on Cyber Monday 2011 was the impact of a “$20 for $40 at” promotion on Google Offers.  Google Offers users experienced various types of errors in completing the offer purchase for about 30 minutes. In addition Newegg website experienced excessive slowness or was unresponsive for more than 1 hour during the promotion.
