Identical Cygwin websites - differing downloads

Identical Cygwin websites - differing downloads

When looking for the latest Cygwin installer, I came across two different domains.

One insecure:
http://cygwin.org/

and one secure:
https://cygwin.net/

When checking the downloaded latest 3.4.6 installer with sha512sum.exe, I get differing checksums from the executables from both websites:

an unexpected checksum (from first site)
787c46173f5f91d350d31053f09d2bc18e1a80907a9f571f905fa7579cd2fa7b2502337da57aa70a5c8c4209a365f3604cee3c8ffe6c451b397986ddf17eea14

and the expected checksum from the 2nd site (as printed on both pages):
4779bead277ba7e682212ed3b1c9c2a56f9b15586dc2db3949556958b683b6f8a11c1c8957e1027d798281fcc98ccf12c418a609911c7e553787c88f8af86152

The first file size shows 1350kB, the 2nd 1356kb.

Can somebody clarify, if cygwin.org is a phishing site or otherwise explain the differences?

all sites point to the same address and all works with HTTPS
IPv4 address (8.43.85.97)

problem/cache in the middle ?

or Corporate/ISP proxy interfering?

As noted in the FAQ and the added footers, cygwin.com appears to be the 
preferred site, so should be used in preference to alternative aliases to avoid 
any possible issues.
