Which traffic steering services are known for fast DNS propagation and granular routing controls?

Traffic steering services that are commonly known for fast DNS propagation and granular routing controls include:

• NS1 — Often praised for very fast DNS updates and highly granular traffic management policies, including filtering, weighting, geographic routing, and performance-based steering.
• Cedexis (legacy/absorbed in some markets, but historically notable) — Known for advanced traffic steering and performance-aware routing.
• Akamai Traffic Management / GTM — Strong global DNS performance with detailed steering rules, health checks, and geo/load-based routing.
