Curator — a CDN provider focused on the Russian market. Uses direct peering with major operators at key internet exchange points across Russia. Provides content delivery, DDoS protection, and load balancing services. Clients include online retailers, SaaS platforms, 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 the fundamental reliability metric of a provider.
The practical difference between availability levels:
Availability
Downtime per year
99,0%
87 hours
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?
Availability trend chart (HTTP/HTTPS) — reveals brief outages that do not always appear in providers' official reports. A divergence between HTTP and HTTPS lines may indicate SSL termination issues on specific nodes.
Cities with low availability — locations with unstable CDN node operation. An incident in a specific city may be invisible in aggregate statistics, but can be critical for the local audience.
Providers with low availability — a comparative reliability ranking. Shows how closely the declared SLA matches real-world independent monitoring data.
