Subject description: when specific websites seem to be down
 

Some times you are trouble to reach some of the sites due to DNS issue, it may be your local DNS cache was corrupt. For this kind of situation, you need to restart your operating system DNS caching service.

For Dog users, type in terminal :

$ sudo /etc/init.d/dns-clean start

There are other ways for flushing DNS cache, but Dog users need only using above command line. You know your DNS cache is flushed if Restoring resolver state... [ OK ] is showing.

If, after flushing your DNS cache, you still have a problem reaching a specific website, try using a public DNS (Google : 8.8.8.8 and secondary DNS 8.8.4.4).

Note :
Having trouble reaching Distrowatch, i tried flushing DNS cache. This is a first step to solve the problem. It was met with success.

To be sure a website is down, look here :

It said : Distrowatch.com is UP and reachable.
