Gomez.com, one of the many analysts sites tracking Web-site uptime, reported that Dell, Victoria’s Secret and Williams-Sonoma’s websites all experienced issues during the morning of Cyber Monday.

In addition to Dell and Victoria’s Secret having issues, Williams-Sonoma’s website experienced slowdowns at the shopping cart/view payment pages with a typical transaction slowing from 26 seconds at 6 AM ET to almost 50 seconds between 7 and 9am ET. The site returned to a steady 24 second response time at 10 AM ET.

Dell’s website returned an error to returning shoppers between 9.40AM to 10.15 AM. Shoppers were unable to retrieve pre-populated account information, meaning they had to fill out forms again when checking out. The issue was quickly resolved, Gomez.com said.

Over Friday and Saturday, Gomez noted issues with Costco, Hewlett-Packard, Overstock.com, Sears, and Staples. Only Costco reported an ‘availability problem” where the site wasn’t available to all users; the other sites merely experienced slowdowns, Gomez found.

How much money was lost during these outages? No one knows for sure, but the math is quite simple: website down, revenue lost, shoppers go elsewhere.
