Overview
Fastly is a global content delivery network (CDN) and edge cloud platform founded in 2011, headquartered in San Francisco, USA. It focuses on delivering fast, secure, and customizable content delivery and edge computing services. Fastly serves a range of enterprise customers, including The New York Times, GitHub, Spotify, and Pinterest, with a developer-centric approach. Its platform emphasizes real-time control, analytics, and edge computing capabilities. Fastly went public in 2019 and remains active, though it has faced challenges with outages and industry slowdowns.
Level3, originally Level 3 Communications, was a multinational telecommunications and internet service provider that operated a global Tier-1 network and content delivery network (CDN) until its CDN services were discontinued in 2023. Acquired by CenturyLink (now Lumen Technologies) in 2017, it provided core transport, IP, voice, video, and content delivery for medium-to-large internet carriers. The CDN focused on video delivery, large object caching, and edge computing, serving clients across North America, Latin America, Europe, and parts of Asia. Level3’s CDN is no longer active, and its network assets are now managed under Lumen Technologies.
Network & Architecture
Fastly operates over 60 points of presence (POPs) globally, with a focus on major population centers for low-latency content delivery. Its global anycast network optimizes routing, but its smaller POP count compared to competitors like Akamai or Cloudflare may limit coverage in some regions. Fastly has strong peering agreements, enhancing performance for high-traffic sites. It excels in North America, EMEA, and APAC but has less presence in Africa and LatAm. The platform leverages WebAssembly for edge computing isolation and resiliency.

Integrations & DevEx
Fastly supports Terraform for infrastructure-as-code, with recent updates like the Terraform Provider 7.1.0 adding domain metadata and IPv6 preferences. It offers SDKs and APIs for custom integrations, CI/CD pipelines, and real-time analytics. Realtime logs and log-push capabilities integrate with monitoring tools like Splunk or Datadog. Migration tools are limited, but the API-first design simplifies configuration for developers.

History & Notes
—
Level3 was a major player in the CDN market, leveraging its Tier-1 network to deliver high-performance content delivery, particularly for video and large files. Its acquisition of companies like Genuity, WilTel, and TW Telecom expanded its footprint, but the 2017 merger with CenturyLink shifted focus to broader network services. The CDN’s shutdown in 2023 was part of Lumen’s strategic pivot, though specific reasons for discontinuation were not publicly detailed. Some network assets may still support Lumen’s non-CDN services.
