Sorry for the long QRX - too busy to update this blog for months!
I've found a spare moment to catch up on my reading and checked the ARRL site for QST. Seems they have changed to a new online provider "Pagesuite".
I was hoping that might dispense with the annoying page-turning junk that so many online magazines seem to think is neat (hint: this is 2017, not 1817!) so I clicked the September 2016 QST cover to check it.
The ARRL QST link took me to the Pagesuite.UK website, with the login screen shown above ... but I don't have credential for that site, and anyway I noticed that it is an ordinary HTTP page, not HTTPS.
ARRL members who don't notice that may well be submitting their credentials (for Pagesuite or maybe for ARRL) over an unencrypted link.
There is no "Register" option on the Pagesuite screen, so I'm stuck at this point: I can't read QST online any more.
The QST logo too ages to appear too, so I get the feeling their webserver might be a thing, maybe a lightbulb in someone's bedroom.
Back to the drawing board, ARRL!
