RE: Rick Furr's www.vcalc.net: Is it gone?
In this case my DNS cache is not causing the issue.
This seems related to a blocking rule somewhere on specific Internet routes.
This issue started a few days ago on my ISP.

As I mentioned above, I can successfully ping (ICMP protocol) the site using the correct URL that resolves to the mentioned IP address:

C:\Users\Suna\Desktop>ping http://www.vcalc.net

Pinging http://www.vcalc.net [216.252.197.18] with 32 bytes of data:

Ping statistics for 216.252.197.18:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 133ms, Maximum = 137ms, Average = 134ms


However the HTTP access gives me a timeout, so in this case the problem is not at the DNS resolution.

And yes, the access works fine using a public proxy server, but that should not be needed in normal situations.

Two questions if I may:

1. Are you able to access the site from a PC behind a NAT firewall?
That's what I have at home: A firewall appliance allowing all my private devices to access Internet using NAT and blocking all external devices from initiating a session with my private devices.

Additional info:
Right now I am connected directly to the ISP router and the issue remains. So it is not caused by my firewall.



2. Can you check what IP address are your systems using to reach the destination?
Is it this 216.252.197.18 ?
