ERROR condition detected - DNS query latency

Hello,

"Responses from the DNS server(s) that the Shophos Web Appliance is using are taking longer than expected (18.0 s), which may result in slower web browsing."

I am continuously getting above alert mails from my Sophos Appliance, plz help me how to correct this

Regards,

Pavana

Further to Tom's comments:
This alert is generated as follows:
Every 1 minute, the web appliance measures how long it takes to do an A record lookup (bypassing local cache) for wsa.sophos.com.
Every 5 minutes, the web appliances takes the last 5 lookup time values, removes the highest value and calculates an average.
The web appliance looks at the current and the last two average values, if they all exceed one second (three in a roll), then the web appliance sends back a notification.
In order for these alerts to go away, whichever DNS server you have is taking a long time to resolve wsa.sophos.com. This would need to be resolved on your end.
Cheers,
MarkJD.
