Q: safari can't find server

It could be many things including a slow DNS server.

Open System Preferences/Network and change the DNS server to 8.8.8.8 and hit Apply.

(Presumably you regularly empty your Safari cache by deleting the following file:

Home/Library/Caches/com.apple.Safari/cache.db

and clear your History)

Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security, (including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat ) and further independent information can be read here:

Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

208.67.222.222

208.67.220.220

(You can also enter them if you click on Advanced and then DNS)

Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:

Safari 5.0.1 or later: Slow or partial webpage loading, or webpage cannot be found

Neville Hillyer advice worked for me. Thank you !

The Advice Klaus1 gave worked for me. Specifically, this part:

Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

208.67.222.222

208.67.220.220

UPDATE: I spoke too soon. I removed those and it worked again. Back to the drawing board.

Thank you.

I suspect that your DNS cache gets flushed each time you change your DNS server.

I flush my DNS cache about once a day - others wishing to do this can Google it.

Nevs - You're an absolute Champion mate!  You solved my problem.  I'm in Cambodia - and it's been driving me nuts. Must be lucky number 8!

Thanks heaps!

Kindly,

This solved my Problem! Thank you.

Nevs - Thanks here as well.  I didn't add the addtional DNS just flushed the cache and problem solved.

Thank you, Neville. Your solution seemed to work for me. I haven't had any "can't find the server" complaints for over a day anyway. Thanks so much for sharing this with us.

thanks the DNS reassignment solved the problem!

Thanks Neville, so far, it has worked for me.

Thank you Neville, it works !

Very helpful..Thanks
