I've had a problem today with a lot of browser pages never loading and a seeing a message 'waiting for ajax.googleapis.com'.

I finally found discussions which tell me the ISP is very likely having a problem with their DNS service. One discussion at PC World said the ISPs usually don't pay much attention to the DNS service and it would be better to just change what is the default DNS service. The article goes on to suggest using DNS Benchmark to find a better DNS service.

Any one use this tool and have you successfully used a different DNS service?

TIA

I have not used the benchmark, but I have used alternate servers for nearly 10 years.

I posted some information before, most recently here:

When I suspect DNS probs I switch to google public DNS

I have run the DNS Benchmark program a couple of different times at different locations, and the Google public DNS that Ralph listed were in the top 5 both times. So I'm pretty sure you probably won't go wrong using those.

DNS Benchmark reported that NTT and Google had the top two DNS servers for my situation.

Router has been updated and rebooted. So far, it appears to have addressed the problem.

TTFN!

Most folks are NOT going to understand this!
Google runs a host of tools for users that come from a variety of IP ranges, however the Google indexing bots are confined to a smaller range.
Many webmasters deny access by the Google tool IP ranges and restrict Google access to Google indexing bot ranges.

The primary Google ranges are 66.249.64 thru 95. 0-255
The Google indexing bot ranges are 66.249.64 thru 79.0-255

Google has other IP's they use as well that are specifically beyond the ranges of their site indexing. Some recent activity is in the Class A 104.

Use of DNS servers may in fact place your access in a 'tools category' and get you denied access from some sites.

Google, along with a variety of mobile devices are using 'Cloud ranges' that are beyond the normal Google IP ranges (i. e., leased lines or other service providers). Cloud ranges may also result in access issues.

Just saying!
