Other than a couple of acquisitions and Yahoo!'s (YHOO) site being down for a substantial amount of time, there was little to spark the Internet sector today and trading was decidedly mixed.

TheStreet.com Internet Sector

index, or DOT, closed down 3.07, or 0.3%, at 1137.19. The minor losses came despite gains in the broader technology sector. The

Nasdaq Composite Index

added 77.29 points today.

Yahoo! generated some much-needed excitement when its site had problems, but the outage took its toll on the stock. Yahoo! finished up 1/2, or 0.1%, at 354, coming back from a low of 347 after the outage was reported, though it traded as high as 363 earlier in the session.

A Yahoo! spokeswoman said the site was down intermittently beginning around 10:45 a.m. PST, and it was back up around 1:25 PST. "We haven't firmly identified the cause. As you can imagine, our engineers are working vigorously to identify and remedy the situation," the spokeswoman said before the site was back up. Note that

CNBC

was reporting that

Schwab's

(SCH)

online trading site was having problems as well today, and the company canceled after-hours trading. Schwab still managed to finish up 7/8, or 2.3%., at 38 13/16.

In regard to the buyouts, companies that were being acquired soared, while those that had to put up the cash, or stock, saw short-term losses for what they hope will be long-term gains.
