Use other mixer, i dont know how you can have situation like this twice within 6 days. What is this? hot wallet not being refilled? Applications stopping to work?
Probably is related to the DDoS? Servers don't run properly when they keep getting flooded by fake traffic.
Mixer is unreachable also due to DDOS for past few days (502), so i guess author does not care..
Doesn't care about what? There is literally nothing he can do to mitigate these DDoS attacks. And it's way better to keep getting DDoS'ed them to implement a MITM protection that will track you and give your data to the gov.
and he made enough money from it already, should be warning sign for this mixer already.
And can keep getting more. As explained by malevolent above, he spends $60k worth of BTC per month in their signature, got hold of hundreds of BTC at once multiple times and can still keep running after 2 years. He is probably making some cash, right? So why stop when you have the reputation and a pretty good margin of profit?
