SAN FRANCISCO -- Yet another e-commerce titan suffered a breakdown today, this time it was

Amazon.com

(AMZN) - Get Report

.

Bill Curry, director of public relations for Amazon.com, told

TheStreet.com

the site was down for 36 minutes, and the company had identified the source of the problem, but refused to disclose what it was. A notice on Amazon's site said that its books, music video, toys and electronics stores were temporarily closed. "We expect to be back soon," a note read, and users were able to leave their e-mail address if they wanted to be notified when the site was back up.

TheStreet.com

received such a notice at 3:58 p.m. EDT.

The problems come during a week when Amazon expanded its site with shopping areas for electronics and toys. And on Wednesday, the company said it had bought a 49% stake in

Gear.com

, an online seller of sporting goods at closeout prices. Nevertheless, Amazon.com was one of the bright spots in the Net sector today, and closed up 4 9/16, or 3.4%, at 139 9/16.

It is the latest in what have been a string of technical

problems for a number of Internet sites of late, most notably

eBay

(EBAY) - Get Report

, which has had technical difficulties on three separate occasions in a little over a month, and

E*Trade

(EGRP)

, which went down last

week. Ironically, Amazon.com's auction site was not down.

There was good and bad to report on the earnings front. Both

EarthLink Network

(ELNK)

and

Inktomi

(INKT)

bested earnings estimates on Wednesday, but closed lower today as traders took profits after-the-fact. EarthLink closed down 3 7/8, or 6%, at 60 1/8, while Inktomi finished down 4 1/2, or 3.5%, at 124 3/8.

After the close,

CNET

(CNET) - Get Report

reported

pro forma

net income of 7 cents a share for its second quarter, 2 cents better than the

First Call

estimate of 5 cents a share. In advance of the report, CNET closed up 1 1/8, or 2%, at 51 7/8. Revenue were $25.6 million vs. $13.3 million in the second quarter of last year and $19.6 million in the first quarter of this year.

And shares of

America Online

(AOL)

were weaker on news that the stock was dropped from the top-10 holdings of some

Fidelity Investments

funds, including the flagship

Magellan Fund

. Fidelity doesn't say whether changes in its list are due to buying or selling, but reports said the move in AOL likely was due to selling. It finished down 2 1/16, or 1.7%, at 120 15/16.
