[squid-users] Unable to determine IP address from hostname ?

[Mirza Dedic]

I have users getting quite frequently this error in Squid..

Unable to determine IP address from hostname.
"The DNS server returned no DNS records"

I have in my squid.conf setup..

dns_nameservers 8.8.8.8 8.8.4.4
dns_timeout 5 second

It seems random, but 5 seconds should be enough and we're resolving against
Google public DNS servers.

The sites it is unable to resolve are up (expedia.com, and other sites that
usually don't go down).

Is there anything else I can do?
