As previously reported, Orbitz enjoyed the biggest e-commerce launch since 1999, but this success brought access problems in its wake

The site had to be taken down on several occasions for upgrades. In addition, an outage caused by a severed fibre optic cable revealed insufficient network redundancy, but improvements have been made. Keynote Systems, a performance measurement company, said that between 3rd July and 9th July, visitors to the site could access it more than 99% of the time, taking between 2.89 seconds and 3.76 seconds. That compares with access times of between 4 seconds and 5.3 seconds in early June.
