EdgeCenter — a Russian CDN provider and cloud platform. In addition to content delivery, it offers DDoS protection, cloud hosting, and DNS services. The infrastructure is built on Anycast routing and is actively expanding across Russian regions and the CIS. Targeted at technology companies and projects with high fault-tolerance requirements.EdgeCenter is actively expanding its geographic footprint, including in CIS regions. When a new node comes online, TTFB in the corresponding region drops sharply — this is clearly visible on the historical chart. If your audience is located in the provider's actively growing regions, TTFB will improve over time.
What is TTFB and why measure it?
TTFB (Time To First Byte) — the time from sending a request to receiving the first byte of the server's response.
Includes RTT, TLS handshake, and CDN-side request processing time.
TTFB directly affects:
page load speed as assessed by Google (Core Web Vitals)
website rankings in search results
the user's perception of site speed
Google recommends keeping TTFB below 800 ms. Values above this threshold negatively impact search rankings.
What do the TTFB charts show?
Average connection time trend chart (HTTP/HTTPS) — the difference between HTTP and HTTPS reflects the overhead of the TLS handshake. A large gap between the lines indicates a suboptimal SSL configuration on the provider's edge servers.
Cities with high TTFB — locations where the CDN server processes requests slowly. May indicate insufficient capacity at regional nodes or frequent cache misses.
Providers with high TTFB — a comparative response speed ranking. Low TTFB correlates with better search rankings and higher conversion rates.
