Dotcom job cuts rocketed 62 per cent in October to 4840 from 2986 in September, marking the first monthly increase since April, according to outplacement firm Challenger, Gray & Christmas (CGC).
Heaviest hit were travel sites and the business-to-business (B2B) sector. CGC said that 2055 dotcom jobs were cut at consumer services firms, such as travel-related sites, which accounted for 42 per cent of the monthly total.
Technology firms came in second with 1140 cuts, while the professional services/B2B sector suffered 1001 layoffs, according to the study.
October's figures brought the job cut total for the year to 95,621, 130 per cent more than last year's 41,515. In addition, the 10-month total is 335 per cent more than the January to October period a year ago, when internet companies laid off 21,966 workers.
John Challenger, chief executive at CGC, said that several companies attributed a marked drop in business to the ongoing economic uncertainty, which only worsened after 11 September.
According to Challenger, the impact of the terrorist attacks has rippled through the dotcom sector as it has in almost all industries.
"Websites specialising in airline reservations and travel planning experienced a substantial fall-off in business, which led to more than 800 cuts," he said. "As companies continue to cut back in online advertising, websites are reducing their business with vendors."
However, the October total fell just short of the 4899 layoffs recorded in August, and is less than the totals for July (8697), June (9216), May (13,419) and April (17,554).
Challenger also pointed out that some industries, such as security, defence and military, are growing.
