Q. Why is Ping Slow Or is it me only ?
A. BulkPing.com Ping all Url's from Serverside i.e. mysql based because it has to be run via private proxies. Ping Sites who do it fast do it on browser side & its not effective & ITS IMPOSSIBLE get successful results by PINGING even 100 urls with same IP to engines (They are SMART).
Q. How many Url's I can ping ? :
A. UNLIMITED, YES you read it right Just upload domains in text file and u are done, will take few mins to few hours as per Queue or Proxy available. We got bunch of 2500 Private Proxies from 12 Countries.
