What do you think happens to the nameservers on the net when they're asked for a domain that doesn't have functional servers, and they sit and churn trying to resolve the names? BTW, churn is the right word. Its taking anywhere from 5-10 *seconds* to come back as NXDOMAIN on each request for those that fail to resolve, and this is from the IANA roots. This IS a functional problem - and worse, all those non-existant zones and the VM churn they generate on the COM TLD servers is probably the REASON that we're looking at this kind of horrid performance! -- -- Karl Denninger ([email protected])| MCSNet - The Finest Internet Connectivity http://www.mcs.net/~karl | T1's from $600 monthly to FULL DS-3 Service | 99 Analog numbers, 77 ISDN, Web servers $75/mo Voice: [+1 312 803-MCS1 x219]| Email to "[email protected]" WWW: http://www.mcs.net/ Fax: [+1 312 803-4929] | 2 FULL DS-3 Internet links; 400Mbps B/W Internal - - - - - - - - - - - - - - - - -
