Why did my tracking work yesterday but not today?

Quick Answer

Overnight changes are usually caused by automatic updates (WordPress, plugins, or themes), ad blocker filter list updates that added new rules, SSL certificate expirations breaking secure requests, CDN cache purges serving different content, or consent platform configuration changes that took effect at midnight.
