Hi,
I have been getting Unknown Host error when trying to access this site intermittently.
This error occurs only on that specific X network.

However the site works perfectly fine on my home network.

I am no interweb expert, but is the site reachable via all the DNS servers?

Regards,

Yes, of course. Can you trace route?

Error on web browser

Description: Unable to locate the server named "www.ibmmainframes.com"
--- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.

Seems like a momentary problem in your ISP's DNS cache. Anyone else facing this issue?

The solution for those who are getting "Unknown Host" error and "502 Bad Gateway" error:

Please clear your browser cookies and restart the browser. The site works fine.

For some reason, I still am receiving Unknown Host from that specific network.
I ate all my cookies, still the same error.

Can you access the site using our IP address from that specific network.

Thank you, the IP technique works fine.
Just replacing the ibmmainframes.com part with IP works fine.

I will edit my local Drivers\etc\hosts file with the above ip address, so the DNS translation does not cause issues. Thanks.
