# Site has not updated

Each DPG site should have two hosts - a **public** one and a **testing** one. If you have made changes, but don't see them reflected on the public address - check your testing site. The testing address is not cached and will update in real time. 

> ⚠️ **Warning:** Testing hosts are not indexed by search engines and are slower than public hosts, so you should avoid sharing testing addresses publicly.

### Finding your testing address

You can find your site's addresses in the **Hosts** tab on the website screen.

### The public host
The public host exists behind a cache layer which updates adaptively depending on traffic. During low traffic these updates will be fast, but once it hits a certain threshold it starts caching more aggressively. Cached pages are then updated in the background so that visitors always land on a pre-rendered page. This allows the site to be stable even under extremely high traffic.
