There's some awful tinpot domain registrars out there where you have to wonder if their whois server is on the end of a dialup link, but fortunately I'm not attempting to access those. Connectivity from here to the CRSNIC server is good and no worse than to any other server I may wish to query for purposes of black- or greylisting.
Doing live queries of domain names like that, on the fly - even if you cache lookup data - will lead to your IP getting rate limited or even blocked by most whois servers, unless you register your IP with them for doing bulk whois lookups. srs
