WordPress CDN Guide: What a CDN Helps — and What It Does Not
A CDN places cacheable content closer to visitors, reducing network distance and origin work for suitable requests. It does not magically fix slow database queries or badly built pages.

Work through the problem in order
- Know which content is cached.
- Check cache-hit behavior.
- Understand purge/invalidation.
- Keep origin performance healthy.
- Test from locations relevant to your audience.
Where hosting enters the picture
WPX includes its own XDN/CDN in current plan materials, which reduces the need to source a separate basic CDN for many users.
