ISNIC is blocking Island WHOIS

Question

Hi,

I have 7800 Icelandic domains to check , however after some checks every respond was an error from isnic . Is it possible to overocme this ? (maybe i could use my own proxies , passing them as parameters? )

Hi , indeed i do need extended WHOIS info . 
Should i try making a pause between requests ? (for how long ?)

Apparently they limit/throttle IPs due to limited bandwidth. Such volumes can't be handled by a regular WHOIS server. Do you need WHOIS or just availability?
