I used chrome to access the website for first time and it says "This site's security certificate is not trused" and this site is meta.travel.stackexchange whereas the certificate is from *.stackexchange.com. I need to click proceed to open the website.
I tried to visit the site from google result for this url,
https://meta.travel.stackexchange.com/questions/1288/suspicious-request-after-logging-in
and redirected to this url,
https://travel.meta.stackexchange.com/questions/1288/suspicious-request-after-logging-in
Other stackexchange sites don't show this message.
Chrome: 59 version
