Some investors/readers probably are not aware that the internet -- critical as it is today for commercial activities and the flow of information -- was not designed to handle the volume and complexity of today's web tasks. Moreover, the appearance of internet traffic jams created an opportunity for Akamai Technologies.

Akamai Technologies (NASDAQ: AKAM) solutions accelerate and improve the delivery of internet content and applications.

Analysts like Akamai's broad 1,800-member customer base, including many blue-chip companies. Further, analysts also like the fact that AKAM has continued to deliver material revenue increases and earnings gains, despite expansion/infrastructure investments.

Further, the consensus among analysts is that 28,000-server Akamai will continue to have a competitive advantage in its key business segments for at least the next two years. The Reuters F2008/F2009 EPS consensus estimates for AKAM are $1.68/$2.04.

MOST NOTEWORTHY: Limelight Networks, Diebold and Charles & Colvard were today's noteworthy upgrades:

• Jefferies upgraded shares of Limelight Networks (NASDAQ: LLNW) to Hold from Underperform on valuation and believes it impossible to know what will happen to the company from here. On the downside, Jefferies notes a permanent injunction means the business is nearly worthless, but on the upside, is the possibility of sale to Akamai (NASDAQ: AKAM) or a large telecomm service provider.
• Baird raised Diebold (NYSE: DBD) to Outperform from Neutral citing expectations of a higher bid from United Technologies (NYSE: UTX).
• Merriman upgraded shares of Charles & Colvard (NASDAQ: CTHR) to Buy from Neutral on valuation, as they believe the current share price does not account for the potential wholesale value of the company's manufactured inventory and method patent. They believe Charles & Colvard is a potential acquisition target.

OTHER UPGRADES:

Level 3 Communications (NASDAQ: LVLT) is one of the most widely traded and widely shorted stocks of any listed on a U.S. exchange. Average daily volume in the shares is over 41 million, and shares sold short as of mid-December were over 167 million. That is tops of all companies listed on the Nasdaq.

Level 3 would appear to be in a good business. It has 50,000 miles of IP backbone to transport voice, data, and video. It provides services to the country's largest cable and telecom companies.

Level 3 has taken a beating in 2007 falling form $6.80 to just above $3. Wall Street has to wonder how it gets back toward $7.

For starters, the company has to stop making an acquisition a month. The company's Level 3's latest 10-Q lists seven deals. It is not unfair for Wall Street to be concerned about the pace of these purchases, especially since Level 3 does not make money. In the September quarter, the company had an operating loss of $53 million on revenue of $1.061 billion. Level 3 also made $138 million in interest payments on its $6.8 billion in long-term debt.

Akamai Technologies Inc. (NASDAQ: AKAM) stock is declining today after an analyst with Cowen & Co. cut his rating of the stock to "Neutral" from "Outperform" this morning on fears of increased competition. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on AKAM.

After hitting a one-year high of $59.69 in February, the stock hit a one-year low of $27.75 in September. This morning, AKAM opened at $36.01. So far today the stock has hit a low of $34.53 and a high of $36.35. As of 11:55, AKAM is trading at $34.68, down $2.42 (-6.5%). The chart for AKAM looks bullish and steady, while S&P gives the stock a negative 2 STARS (out of 5) sell rating.

For a bearish hedged play on this stock, I would consider a February bear-call credit spread above the $45 range. A bear-call credit spread is an options position that combines the purchase and sale of call options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 7.5% return in two months as long as AKAM is below $45 at February expiration. Akamai would have to rise by more than 28% before we would start to lose money. Learn more about this type of trade here.

With the credit crunch, it seems that private equity is losing its luster, right? Maybe not. After all, with better valuations, the opportunities may be looking good.

Today we learned that the vice president and chief financial officer of Internap Network Services (NASDAQ: INAP), David Buckel, is leaving. And, yes, he's exploring opportunities in the private equity space.

Buckel has spent four years at the company, which is an operator of a content delivery network (CDN). Basically, this allows for improved distribution of online content and applications. There are more than 3,500 customers and revenues increased 32.7% to $60.9 million in Q3.

No doubt, this is far from good news for Internap. Keep in mind that the company must compete against fierce rivals, such as Akamai Technologies (NASDAQ: AKAM) and Limelight Networks (NASDAQ: LLNW). In fact, there are some signs of a price war.

So far in today's trading, Internap's stock is down nearly 8% to $10.82.
