08 · FAQ

Frequently asked questions.

Complex HA architecture? Our network engineers can help.

L4 (TCP/UDP) routes at the transport layer — fast, ideal for databases and gaming. L7 (HTTP) inspects requests and routes by URL, header or cookie — perfect for APIs and microservices. Our LBs support both simultaneously.

No. Inbound and outbound traffic through the load balancer is unlimited and included in the price. You only pay for the chosen plan, not bandwidth.

Health checks (HTTP, TCP or custom) detect a failing backend in < 500ms. Traffic is redirected to healthy backends in < 1 second. No manual intervention needed.

Yes. Import your EV or custom certificates, or use our automatic Let's Encrypt integration with renewal. The LB-GLOBAL plan additionally supports HSM-stored certificates.

Yes, from the LB-ENTERPRISE plan. Full WebSocket support with sticky sessions and dedicated health checks. The LB-GLOBAL plan adds gRPC and HTTP/3 (QUIC).
