ByDanicaKirkaand David Koenig The Associated Press LONDON Twelve hours af- ter a power outage knocked out its computer systems worldwide, Delta Air Lines was struggling Monday to resume normal operations and clear backlogs of pas- sengers stranded by can- celed flights. By early afternoon, Delta said it had canceled 451 flights. Tracking service FlightStats Inc. counted 2,000 delayed flights — about one third of the air- line's entire schedule. Delta representatives said the airline was investi- gating the cause of the melt- down. They declined to de- scribe whether the airline's information-technology system had enough built- in redundancies to recover quickly from a hiccup like a power outage. Many passengers were frustrated that they re- ceived no notice of a global disruption, discovering that they were stranded only af- ter making it through secu- rity and seeing other pas- sengers sleeping on the floor. Delta said that the outage caused a lag in post- ing accurate flight-status information on its website. At noon inside New York's LaGuardia Airport, Francesca Villardi still had no idea when her 11:50 a.m. flight to Fort Lauderdale, Florida, would depart. The departure boards said her plane was leaving on time. She received dif- ferent answers from three Delta employees, one of whom said she would be traveling to Cincinnati first. "This is not organized at all," said the 51-year-old professional organizer from Pembroke Pines, Florida. Delta said that almost 1,700 of its scheduled 6,000 flights had operated by mid-afternoon. The air- line posted a video apology by CEO Ed Bastian, who stood in the airline's tech- nology center and assured customers that employees were working hard to re- sume normal operations. A power outage at an Atlanta facility at around 2:30 a.m. local time ini- tiated a cascading melt- down, according to the air- line, which is also based in Atlanta. A spokesman for Geor- gia Power said that the company believes a failure of Delta equipment caused the airline's power outage. He said no other customers lost power. Delta spokesman Eric O'Brien said he had no in- formation on the report and that the airline was still in- vestigating. Flights that were already in the air when the outage occurred continued to their destinations, but flights on the ground remained there. Airlines depend on huge, overlapping and compli- cated systems to operate flights, schedule crews and run ticketing, boarding, air- port kiosks, websites and mobile phone apps. Even brief outages can snarl traf- fic and cause long delays. That has afflicted airlines in the U.S. and abroad. Last month, Southwest Airlines canceled more than 2,000 flights over several days after an outage that it blamed on a faulty network router. United Airlines suffered a series of massive IT melt- downs after combining its technology systems with those of merger partner Continental Airlines. Lines for British Air- ways at some airports have grown longer as the carrier updates its systems. On Monday in Richmond, Virginia, Delta gate agents were writing out boarding passes by hand. In Tokyo, a dot-matrix printer was resurrected to keep track of passengers on a flight to Shanghai.

By Seth Borenstein The Associated Press WASHINGTON Rising global temperatures are clearly linked to increasing waterborne food poison- ing, particularly from eat- ing raw oysters, along with other nasty infections, a new study shows. About a dozen species of vibrio (VIB'-ree-oh) bacte- ria make people sick from eating raw or undercooked seafood or drinking or swimming in tainted wa- ter. It also causes cholera, although that was not the focus of the research. Lab-confirmed vibrio infections in the United States have increased from an average of about 390 a year from the late 1990s to an average of 1,030 in re- cent years, according to the Centers for Disease Control and Prevention. But most cases aren't confirmed by tests and reported. "It's a remarkable in- crease on an annual basis," said study lead author Rita Colwell of the University of Maryland, a top microbiol- ogist who used to head the NationalScienceFoundation. The study examined Eu- rope and North America, but the most consistent tracking of vibrio illnesses were in the United States. The CDC blames about 100 deaths a year on vibrio on average. Even Alaska, where such outbreaks used to be un- heard of because the bac- teria needs warm water, is getting cases from peo- ple eating vibrio-infected oysters, Colwell said. Her study, published in Mon- day's Proceedings of the National Academy of Sci- ences , highlights an un- precedented wave of vibrio illnesses from swimming in northern Europe during heat waves in 1994, 1997, 2003, 2006 and 2010. Until now, researchers had indirectly linked cli- mate change to an increase in illnesses from the bac- teria, Colwell said. Using DNA, a 50-year database of plankton, water tempera- tures and disease reports, she shows a more compre- hensive connection. "Now we have linked very directly the increase and the trend in number of cases, so it's all coming to- gether in great detail," Col- well said. With the giant database of plankton and DNA, the international team of sci- entists was able to moni- tor how pervasive the vib- rio bacteria have become in waterways around the world by creating an index. The index doesn't show the number of vibrio, but its relative abundance, said study author Luigi Vezzulli of the University of Genoa. That index has about tri- pled in many of the areas they examined, including the North Atlantic. That type of examination of vibrio levels in plank- ton hasn't been done be- fore and "is critical to un- derstand the regional scale of changes in climate to po- tential increases in human risk," said Erin Lipp, a Uni- versity of Georgia, professor of environmental health sci- ences. She wasn't part of the study but praised it as excit- ing and important.
