Yesterday I looked at my traffic and something didn’t seem right. After some investigation I found that I was sending traffic to broken pages; it’s a very depressing situation when you pay for the traffic. Needless to say this is a great method to lose a lot of money.

 
My sites weren’t completely broken, but every other refresh would display “Server Not Found”. This took me a very long time to figure out: First I thought it was the A Records for the DNS, so I changed all my websites’ A Records. Few hours later I was encountering the same problem; that’s when I figured decided to check my nameserver that the site was hosted on. Apparently, it had expired last month and was on redemption period. That would explain why the server wasn’t found, but why was it still occasionally working? DNS records are really complicated and can be masked behind other DNS records; it’s like a map to your website and the map can have different routes to your website. The main routes to my website were expired, but there were other smaller routes; therefore, you could get to my website by taking other routes.

 


 
Yeah.
