What is TTFB by Europe
TTFB by Europe shows the Time to First Byte (TTFB) values broken down by European country. Each row displays the country name, a status color, and the TTFB value at the selected percentile. This shows whether your back-end or CDN delivers fast responses across Europe.
Time to First Byte (TTFB) is the time from request start until the first byte of the response is received.

If countries in Eastern or Southern Europe trend yellow/red, routing or missing edge coverage may be slowing responses.
Resolving unhealthy TTFB by Europe
Go-to action plan to resolve an unhealthy TTFB by Europe:
Ask Uxi to analyze your TTFB by Europe values and suggest improvements.
Use Filters to contrast first vs. repeat TTFB; confirm edge caching warms as expected.
Simulate TTFB of the suspected breakdown to see if fixing it will resolve the TTFB by Europe. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by Europe values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
