Can't access certain sites?

McOz · 10-12-2007, 05:26 AM

A couple of months back, I was unable to access a site or two that were previously ok. Now, I can't even access google? Yahoo will open, but won't search. The blue task bar won't move beyond the address and in the lower left corner, the message is a constant "Contacting www.google.com" (Safari. Firefox and Opera won't open the same pages)
I can successfully ping the particular sites, but that's it. Any ideas???

Does the problem continue from a newly-created user on your computer?

Does the problem continue from another computer on your network?

Can you traceroute to the problem pages? Let us see the traceroute, obfuscating the first couple routable IP addresses shown. (Traceroute can be done from the command line, or if you're more comfortable in the GUI, there's a Network Utility in your /Applications/Utilities folder that can do it as well.)

Also, check your logs for errors. You can easily view logs using the Console app in /Applications/Utilities.

that is way too much latency 1085 ms.

what do the pings look like coming from your isp?
do you have any # listed for a dns server in the network prefs panel?

bramley · 10-12-2007, 12:41 PM

Answering no to both of Trevor's questions suggets that the problem is confined to your current user on the one machine. Probably no connection with your network then.

In Safari, have you tried emptying your cache? See Safari Preferences Menu to do this. If you do this for your current user does that improve things?

McOz · 10-12-2007, 12:55 PM

The other user (wife) has the same problem now accessing the same pages, but she has been a user for ages, long before the problem. Emptied cache to no avail. Should I try from her user account? Can't see why all browsers would be affected though???

appleman_design · 10-12-2007, 02:37 PM

McOz · 10-12-2007, 08:36 PM

Well appleman, that change got enabled me to access google ok. Where was the problem above?
Still can't access the first site that made me aware of the problem, but that's a start!
Thanks

trevor · 10-12-2007, 09:01 PM

appleman_design's suggestion was to change your DNS servers. Since that appears to have fixed the problem, that indicates that the problem is with the DNS Servers that you were using before. You may want to talk to your internet service provider and either find out what DNS Servers that they are using now (in case you had old IP addresses for old DNS Servers in your System Preferences > Network > TCP/IP tab > DNS Servers) or else the mechanism that automatically assigns you DNS Servers from your ISP has bad information. Or else the DNS Servers from your ISP are just screwed up.

Trevor

McOz · 10-12-2007, 09:07 PM

Well, it fixed it for google and related search engines, but not all the sites I've had issues with. As for the ISP, I've gotten more help here in a few posts than the hours spent on hold waiting for their elusive Mac Department!!

McOz · 10-14-2007, 08:09 PM

On a side note to this, I'm finding a lot of sites that won't fully open, in Safari, lower left message reads "completing 36 of 37 items" and that's all. Same sites won't open in Opera or Firefox either. Any more ideas to both issues?

hayne · 10-14-2007, 08:47 PM

In Safari, open the "Activity" window (from the "Window" menu) and look to see what item is not loading.

McOz · 10-14-2007, 10:34 PM

Here's an example, don't know what I'm looking for though. Page half opens, then nothing.

stewiesno1 · 10-14-2007, 11:13 PM

McOz ,I think you may find that it is how Telstras servers and some of the ISP's out here in the colonies handle internet traffic. I used to have a hell of a hard time connecting to three sites ( using Safari ), one of which was Other World Computing. After a couple of months of not being able to go to their site I managed to send an email to their Webmaster complaining that I couldn't access their site. I tried from our neighbours HP Pentium 4 who also had Telstra BigPond broadband cable as well- no go . A couple of days later i got a detailed reply from OWC 's webmaster stating what I said in the opening lines. A few weeks later Telstra changed something about their servers ( I got an email saying words to that effect ) and lo and behold I was able to connect to OWC and the other two sites straight away. if you can connect to http://eshop.macsales.com/Service/webmaster.cfm
and ask them the reason they will be able to give you a better more detailed answer than me. This may or may not solve your problems.
I also had a Telstra tech come out to my place and replace some of the connections outside my place because i was getting a lot of dropouts .

Have you tried connecting with nothing in your DNS Servers Field or Domain Name Field. If not.. give it a try. Its solved a similar prob for me in the past.

McOz · 10-15-2007, 07:54 PM

I had all 0's in the dns 1 & 2 locations at first, changed them according to ThreeDee above's suggestion.
Domain name is still empty.
This is all within the router's ip address.
