Cryptic most likely saw a rise in dilithium earnings in the Foundry since the patch.
They probably will want to lower it to bring it more in line with their player gain-per-day statistics.
Internal sensors showed that players were still having fun and not toiling hard enough, and triggered an emergency shutdown. The devs are hard at work removing any traces of player-benefit by making each mission COST dilth and fleet marks now.
Joke aside it's more than likely just a random server glitch. Happened to crash the Foundry this time that's all.
Hopefully it's back up in a couple hours.
