Avaya is looking to take the lead in enterprise telephony with its $900 million purchase of Nortel’s Enterprise Solutions business. The enterprise business is the latest unit that bankrupt Nortel has sold off this year. Still, despite its efforts to drastically shrink the company, Nortel is continuing to roll out products, most recently announcing a 100G optical solution. Cisco Systems has completed its $2.9 billion acquisition of mobile infrastructure vendor Starent Networks, which will become a key part of Cisco’s new Mobile Internet Technology Group. Google is reportedly brokering a deal to buy local search and review property Yelp for $500 million. The Website had 26 million visitors in the last 30 days through November. Now, if Google can get Yelp, it will have a treasure trove of local information with which it can pair contextual mobile ads. If it goes through this deal would be Google's seventh of 2009, preceded by On2 Technologies, ReCaptcha, AdMob, Gizmo5, Teracent and AppJet, all since August. New details about the attack that disrupted Twitter Dec. 17 have begun to emerge. According to Twitter, the DNS settings for Twitter.com were hijacked, resulting in roughly 80 percent of the traffic from the site being redirected elsewhere from 9:46 p.m. to 11 p.m. PST. Apparently, the attackers got their hands on a valid set of Twitter credentials and used them to compromise the DNS records. A spokesperson for Dyn, the DNS company that services Twitter, said an authenticated user logged into the Dynect platform and redirected the site. As part of the commemoration of the 35th anniversary of the systems, Hewlett-Packard says it is upgrading its Itanium-based Integrity NonStop servers to enable users to increase capacity, improve performance and integrate with such open-source software as Spring and Apache Axis2.
