Identrust is letsencrypt ca.
Most of the ssl certs on the internets are letsencrypt/identrust.
If you are not using ev certs there’s really no reason to pay…
Letsencrypt is designed to cron + renew the cert every 90 days.
The rest of the internet is slowly catching up.
Most places have earlier than usual closing times. Swee choon last order was 1230am. I think alcohol can only be sold til 1030pm. So the eateries don’t keep up either.
