Maybe you noticed the pool website now redirects to https://slushpool.com. The URL is legit, we've been lucky enough to obtain this nice domain and we just moved there from more complicated "mining.bitcoin.cz". Back in 2010 I did not realize how big the mining industry will became, so I choose just a subdomain of my Czech bitcoin blog :-).

This is just about the website, no change in miner settings is needed as we keep all mining URLs to work normally.
