Edge Network Points of Presence
Expedited WAF runs on a globally distributed edge network. Every request to your protected domain is routed to the nearest edge location, where it is inspected for attacks, matched against your rules, and screened for DDoS signatures before being forwarded to your origin. Responses are compressed and cached at the edge.
Edge Network Locations
The edge network runs in the following points of presence, sited at major population centers and internet peering hubs:
North America
- San Jose, CA
- Chicago, IL
- Dallas, TX
- Washington, DC
- Miami, FL
Europe
- London, UK
- Paris, France
- Frankfurt, Germany
Asia Pacific
- Tokyo, Japan
- Singapore
Failover
Traffic is routed to the closest healthy edge location using latency- and health-aware DNS. If a location degrades or becomes unreachable, requests shift to the next nearest point of presence with no configuration change on your end. Visitors keep reaching your site even when an entire region is offline.
Redundancy
Each edge location is built with redundancy at every layer:
- Multiple servers at each location, so a single hardware failure does not take a location offline.
- Redundant network providers at each site, so a transit outage on one carrier does not interrupt traffic.
- Cross-region failover, so that a complete location outage routes traffic to the next nearest point of presence.
- Distributed cache and rule state, so that failover does not require a cold cache or a rules reload at the new location.
