If the main site is down, check the discord channel for a back up: https://discordapp.com/channels/408499477901475840/426403731941097472. However, remember that you can ALWAYS interact with the smart contract directly because the app is decentralized.
There have been many DDOS attacks to the front-end website in order to get people to panic and sell, without even checking the status of the contract in etherscan.io. It seems like people still don't even know what they are putting their money into.
