Very weird. I cannot access the website from this computer. It’s not a route issue, because I can get to it from her Windows machine, but on my Linux machine, it times out. Traceroute output is:

When I ping it, I get this:

When I try to browse to that IP address, I get this:

Your connection is not private

Attackers might be trying to steal your information from 176.32.103.205 (for example, passwords, messages, or credit cards). Learn more

NET::ERR_CERT_COMMON_NAME_INVALID

This server could not prove that it is 176.32.103.205; its security certificate is from *.peg.a2z.com. This may be caused by a misconfiguration or an attacker intercepting your connection.

**************************************************************

Anyone have any idea what might be going on? This only started in the past day or so.

Note: I have the same problem on my virtual Windows machine. I simply cannot access Amazon from this hardware.

[Update a while later]

None of the proferred explanations so far explain why it’s only (AFAIK) amazon.com.

[Afternoon update]

OK, the problem is with ExpressVPN. When I disconnect it, and put Google’s nameserver in /etc/resolv.conf, it works. So I guess I need to talk to them.

[Late afternoon update]

OK, the problem seemed to be the San Francisco VPN server (the default). When I connected to LA instead, the problem went away.
