Q: Why can't I seem to reach wa7v.ampr.org or 44.12.3.128?  Is this system broken?
A: Read this article for the answer.

Well, no, it's not actually broken, but ALWGW's 44.12.3.128 source packets are being filtered by the ISP.  The ISP does not recognize ALWGW's AmprNet address as belong to its own network.  This practice is becoming more common nowadays, as ISPs are taking steps to ensure that hosts from their networks are not spoofing IPs from other networks.  This is normally a good thing, but it poses a problem for AmprNet systems.

In ALWGW's case, you should be able to connect to the net-44 address if you are coming from another AmprNet system.  The 44.x -> 44.x packets will be encapsulated (e.g. tunneled) inside of frames with standard commercial IPs.

If you are not coming from another AmprNet system, you'll need to use ALWGW's commercial hostname or IP, which is gw.wa7v.com or 192.147.172.251.  This will provide you with the same service that you would have gotten from wa7v.ampr.org / 44.12.3.128.  Note: Users' email addresses remain callsign@wa7v.ampr.org, regardless.
