A number of leading websites around the world went offline on Thursday as a result of an internet outage, including the official websites of Delta Air Lines, British Airways, UPS, AT&T and Costco.
“We are experiencing temporary technical issues serving our customers at delta.com and the Fly Delta mobile app … We apologize for the delay and are working to restore the site as soon as possible,” Delta said on its website.
Affected websites load very slowly or cannot load while displaying the message “DNS error” reports BNR.
