Друзья, всем предлагаю зайти на свои сайты и проверить не добавит ли их chrome 17 Апреля в блеклист. В developer tools, console можно увидеть предупреждение, в случае, если google планирует добавить его в недоверенные:

The SSL certificate used to load resources from https://scdn.cxense.com will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See https://g.co/chrome/symantecpkicerts for more information.

On January 19, 2017, a public posting to the mozilla.dev.security.policy newsgroup drew attention to a series of questionable website authentication certificates issued by Symantec Corporation’s PKI. Symantec’s PKI business, which operates a series of Certificate Authorities under various brand names, including Thawte, VeriSign, Equifax, GeoTrust, and RapidSSL, had issued numerous certificates that did not comply with the industry-developed CA/Browser Forum Baseline Requirements.

Вывод: используйте letsencrypt 🙂
