Leonardo De Lima, who works in technology, was on his way to Boston Logan International Airport around 5 a.m. for a business trip to Chicago when he realized his phone was in SOS mode. He initially thought it was a problem with his device, until he got to the Delta terminal and saw a lot of confused faces.
“I heard people talking about the outage, and everyone was lingering in the departure area because nobody could pull up their tickets on their phones,” the 32-year-old said. “I saw a lot of stress.”
