Edge network · 118 cities
Every request meets a bouncer before it meets your server.
Perimeter sits in front of 41,000 origins and answers most traffic without waking them up. Median edge response: 11ms. Median time to drop a bad actor: 0ms — it never gets in.
A grid, not a globe.
118 points of presence, each holding a slice of the internet's traffic close to the people making it. No single dot matters — that's the design.
What happens in those 11 milliseconds
Request lands
Visitor in Manila hits the nearest of 118 cities instead of your origin in Ashburn.

Origin stays quiet
