Operation Supply Drop, an organization that provides games to U.S. troops serving abroad, says that it came under a distributed denial-of-service (DDoS) attack shortly after starting its third annual 8-Bit Salute event this morning.

“Yes, 27-minutes after the official 0800 CST start time of the 3rd Annual 8-Bit Salute, some nefarious creatures took our site down with a DDoS attack,” the organization said in a statement. “Odds are this will happen again over the next 24 hours.”

At the time of writing, the organization’s official site was still down. However, you can still contribute by sending donations to DONATIONS@operationsupplydrop.org through PayPal, or by buying a poster from Rooster Teeth, which will only be available during its 8-Bit Salute stream. All proceeds from the poster will go directly to Operation Supply Drop.

You can also buy a $20 8-bit shirt from SilencerCo, $5 of which will go to Operation Supply Drop.

The Last of Us developer Naughty Dog is also promoting the cause today by playing Uncharted 3’s multiplayer mode with fans. They’ve even reset the game’s leaderboard in honor of the event and will be giving away Naughty Dog games, DLC, and other items to players who donate the most. You can read more about Naughty Dog’s participations in the event on the PlayStation Blog.

“This is a battle,” Operation Supply Drop said. “Let’s show the world what happens when you mess with Gamers!”
