‘Sustained’ cyber attack forces Flightradar24 offline

Flightradar24.com, the popular flight-tracking website, is experiencing “sustained attacks” on its system and remains unavailable for users as engineers try to fix the issue.

“Attacks on our systems continue and while we were able to bring services back for a short time, significant instability due to the sustained attacks has forced us to refocus our efforts to mitigate them,” the website said in a Twitter post. “Flightradar24 remains unavailable to all users at this time.”

No further information was available. Flightradar24 doesn’t have an estimate on when its services will resume as the attacks are preventing it from successfully serving legitimate traffic, a spokesman said in an emailed response to queries.
