PSAs showing on certain pages

Emailed google

[spica42]

3 out of 30 pages on my site are showing PSAs. (index page is one of them) I emailed googled and asked them and this is their reply:

---------------------------------------------------------
Thanks for your email.

At this time, we are having DNS look problems for your domain and our crawlers are unable to reach your site. Please contact your ISP
regarding this issue.

CAn DNS look problems just affect a few pages on the site instead of the whole site? The PSAs have been showing for 7 days.

One thing to note though, I've redirect mysite.com, mysite.com.sg and www.mysite.com to www.mysite.com.sg. Not sure if the problem lies here...

Anyone can help?

I have seen this too.

Time usually sorts it out.

But Google actually said that there might be some DNS problem with my site. I emailed google and got a second reply:

----------------------------------------------------
Thank you for your response.

I have confirmed that the DNS look up issue remains with your domain. In
order to receive properly targeted ads to the rest of your domain and to
resolve the problems with PSAs we will need to be able to crawl your site.
Please contact your ISP to resolve the problem.

Anyone knows what I can do?

Well... err... how about contacting your ISP? :)

ISP means the hosting comapny or the internet service provider?

Also try testing your domain(s) via [dnsreport.com...]

That may provide some data for your ISP to work with, if there is a problem.
