About Curator

Curator — a CDN provider focused on the Russian market. It uses direct interconnections with major operators at key internet exchange points in Russia. It provides content delivery, DDoS protection, and load-balancing services. Its customers include online stores, SaaS services, and media projects. Curator ensures availability through geographic redundancy at the internet exchange point level. If one peering link fails, traffic is automatically rerouted through alternative paths. This makes regional incidents less visible in aggregate statistics, but check the city histogram — local dips are still captured by monitoring.

What is Availability and why measure it?

Availability — the percentage of time the CDN correctly serves user requests. This is a basic indicator of provider reliability.
The practical difference between availability levels:

99,9%8,7 hours
99,99%52 minutes

Even brief outages directly impact revenue, reputation, and search rankings — Google takes site availability into account when ranking pages.

What do the availability charts show?

01

Availability chart (HTTP/HTTPS) — lets you see short-term outages that don't always make it into official provider reports. A discrepancy between HTTP and HTTPS may indicate SSL termination issues at individual nodes.

02

Cities with low availability — locations with unstable CDN node operation. An incident in a specific city may be invisible in overall statistics but critical for the local audience.

03

Providers with low availability — a comparative reliability ranking. Shows how well the declared SLA matches real independent monitoring data.
