Overview
CDNSun, founded in 2012, is a content delivery network provider based in Prague, Czech Republic. It offers services like website acceleration, video streaming, and software delivery through a network of over 50 points of presence (PoPs) worldwide. Its customer base includes businesses seeking cost-effective CDN solutions, particularly small to medium-sized enterprises. CDNSun emphasizes affordability with a pay-as-you-go model and a 15-day free trial. The service supports HTTP/2 and provides free shared SSL on its *.r.worldssl.net domain.
Parler Cloud Technologies, a subsidiary of Parler, operates a CDN through its acquisition of EdgeCast assets from the bankrupt Edgio in February 2025. The service, branded as EdgeCast Cloud Services, focuses on delivering video-on-demand and software downloads, targeting censorship-resistant platforms. It supports Parler’s ecosystem, including Parler Social, PlayTV, and ParlerPay, with a focus on privacy and decentralized hosting. The company positions itself as an alternative to mainstream cloud providers, appealing to businesses and creators seeking scalable, secure content delivery. Parler claims to serve 16 million users across its platforms, though its CDN customer base beyond its own services remains unclear.
Network & Architecture
CDNSun operates more than 50 PoPs across five continents, including locations in North America (e.g., Atlanta, Chicago, Dallas), Europe (e.g., Amsterdam, Frankfurt, London), Asia (e.g., Hong Kong, Singapore, Tokyo), South America (e.g., Sao Paulo), and Australia (e.g., Sydney). All edge servers use SSD drives for faster data access and have redundant connectivity to robust internet networks. The network supports global content delivery with a focus on reducing latency for websites and streaming services. Specific routing or peering details are not publicly disclosed, but the provider claims strong performance for global audiences.
Parler’s CDN operates across 25 points of presence (PoPs) in seven countries, expanded from five North American data centers after the EdgeCast acquisition. As of April 2025, it supports 10 Tbps of network capacity, with plans to scale to 50 Tbps globally by year-end, excluding regions like the Middle East, South Asia, Eastern Europe, Africa, and Australia. The network leverages EdgeCast infrastructure, previously used for high-profile streaming like the Super Bowl, and integrates with Triton SmartOS for cloud orchestration. Specific routing or peering details are not publicly disclosed, but the focus is on optimized content delivery for video and software.
