OAKLAND PARK, Fla (Gambling911.com) - FanDuel's app was down for a good chunk of their customers during the critical hours leading into Sunday's NFL kickoff and many players continue to be irate coming into Monday.
John tweeted: "Unless @FanDuel @FanDuel_Support wakes up and decides to refund the slate, I won’t be able to recommend their DFS product going forward. Completely insane that they’re still radio silent.".
Anthony writes: "They have had real strong issues for the past few years. This one was ultimately the worst as this is the first time you were not able to change your lineup multiple hours before kickoff. A forced line lock at 11am, no piblic announcement, it’s insane."
Nate asked: "How about the fact that they said the entire slate was money back even if you lose and then just didn’t give money back…Utter disaster."
Following Gambling911.com's coverage of this matter, FanDuel responded by confirming they will be issuing refunds to those negatively impacted.
Daily Fantasy Sports (DFS) customers appeared to be affected the most.
To our DFS customers - we acknowledge that yesterday's site issue was unacceptable. NFL Week 1 is supposed to be a joyous time, and we fumbled. The team investigated the issue and has now refunded the net losses to our impacted customers. We remain committed to offering you a…

According to DownDetector, Fanduel users reported problems around 11 a.m. EST Sunday, about two hours before the first NFL Sunday of the season.
There were more than 300 reports of problems, and "Is Fanduel down" was trending on Ggoogle. So was "fanduel content unavailable."
Downdetector reported that the biggest problem was being able to get on the app, and that's where about 70 percent of reports were about. This appeared to be rectified some time after the early 1 pm EDT kickoff.
The period between 11 am EDT and 1 pm EDT Sunday Week 1 NFL is typically the most high demand time frame for sports bettors in North America. During the early 2000's as offshore sportsbooks began to explode in size, with a reliance primarily on bets placed by phones, entire phone banks would crash the hour leading up to the NFL 1 pm EDT games. Gambling911.com was present during the 2000 and 2001 seasons to witness this first hand at what was then the largest offshore sportsbook catering to those in North America.
The situation may not be completely resolved however. The refunds might not be going to everyone affected.
Customers were still fuming Monday evening.
DFS player DougieYaps tweeted:
"For those having a hard time understanding why FanDuel has not made right on the sweat free millionaire contest… imagine I sell you a lemonade. And there’s a special promotion that if you bring back the cup next week, I’ll refill it for free. So you get two lemonades in total. If the lemonade machine is broken this week and all I give you is an empty cup, I can still let you come back next week and refill it, but I’ve only given you half of what I promised. If that doesn’t make sense to you, I suggest choosing a hobby that requires less math. @FanDuel_Support - the arbitrators will understand just fine."
