Network Error

Network Error
 get this error from time to time. I don't believe it's thrown up by my browser, or by the server on the other end but by a router in between. I get this on sites like CNN, eBay etc intermittently. Big sites, that I doubt are suffering downtime. I also get it sometimes on smaller sites.

Can anyone shed some light on the origin of this?

If you reboot the computer it will clear out the DNS cache.

The default time period for keeping an address in the cache is 24 hours. Another more common problem can arise from URLs that are temporarily busy or from congested Internet traffic. If a negative response is received from an attempt to connect, that result is also kept in the local cache. The default time period for retaining a negative response is five minutes
