What breaks at 3am

Most client-side issues are boring failures with expensive consequences.

ssl/expiry
/01

SSL expired silently

Certificate quietly hits its end date. Browsers throw warnings. Your client blames you, not Let's Encrypt.

domain/whois
/02

Domain didn't auto-renew

Card on file declined. WHOIS expiry passes. The site is gone for a weekend before anyone catches it.

dns/changed
/03

DNS quietly changed

A junior dev or migration tool flips an A record. Email starts bouncing. You find out from a phone call you didn't want.
