What Amazon CloudFront does - and how it fails

Amazon CloudFront is AWS’s global CDN - the front door for websites, APIs, and media. Because it runs at hundreds of edge locations, CloudFront incidents tend to be geographic (elevated errors in some regions of the world) or configuration-driven (a bad deployment propagating to the edge).

Elevated 5xx rates at a subset of edge locations
Increased cache-miss rates pushing load onto origins
Slow or stuck configuration/invalidation propagation

Amazon CloudFront questions

Is CloudFront down right now?

Check the live status above - and remember CloudFront failures are often regional at the edge. Testing from another network or region can localize the problem quickly.

How do I tell a CloudFront problem from an origin problem?

Look at the error: 502/503 with an x-cache header of “Error from cloudfront” but healthy origin logs points at the edge; errors that appear identically when hitting the origin directly point at your origin.

Does CloudFront have an SLA?

Yes - 99.9% monthly uptime, with tiered credits on claim when it is missed.
