Problem with cgminer

[7up]

Yesterday i tried cgminer for the first time. It went very smooth but today when i try to run it then it doesn't work
I tried both commands:
1) path to .exe -o http:api.bitcoin.cz:8332 -USERNAME -p PASSWORD
2) cgminer -o http:api.bitcoin.cz:8332 -USERNAME -p PASSWORD

Yesterday one of them (dont remember which) worker correctly. Why it's broken now? I recive error that pool is too low or down but as i see the other people still mine.
As you see im useing https://mining.bitcoin.cz/


Ofc i have newest version of cgminer which i updated today but the older one doesn't work too...

Many pools were DDOSed yesterday, that is the reason you could not connect.
