Managing TLS certificates has become pretty crazy: Over the years validity was cut down from several years to two years to one year to half a year now. In a few years it will be only a little more than one month, with the additional requirement to basically continuously prove domain control.

Since I'm not using Let's Encrypt over here, these days I have to re-submit a CSR to my certificate provider every half a year for every domain, prove domain ownership, install the new certificate (chain), and update my DANE/TLSA records. Soon continuous domain control validation will have to be added as an additional secondary process to the domain reactivation/renewal process.
