I just discovered that typing in https://mysite.com redirects one of my sites which does not have SSL yet, to an unrelated website (hosted by my ISP). Oddly, though, if you click on their link to their home page it sends you back to the current home page of my site.
My ISP is saying:
"As the URL you provided is invalid there is nothing wrong with being incorrectly redirected.
The site you are accessing does “not” have an SSL certificate and therefore the URL: https://mysite.com/ is invalid."
"You are on the same server and they are the closest IP with an SSL certificate. If you have a valid certificate the issue the url would be valid and no problem would be displayed."
Sounds wrong and possibly damaging to SEO. Is this a common practice?
this also sounds similar to the crap that the toplevel DNS servers were doing a while back and what numerous hosting companies have been doing for a while... in those cases, the redirects were to hosting ad pages or to lists of similar related sites or some such...
i'd be checking that TOS and other service documents to confirm...
