Overview

NTT Communications, a subsidiary of Nippon Telegraph and Telephone Corporation, provided a content delivery network (CDN) through its Smart Data Platform, powered by EdgeCast, offering global content delivery for enterprises. The service, launched in 1999, supported various industries with robust network infrastructure until its deprecation in 2025. Following the sale of Edgio’s CDN business, NTT Communications announced the shutdown of its CDN platform, with services ceasing on January 15, 2025. Customers were advised to migrate to Akamai to maintain CDN functionality.
StackPath was a content delivery network (CDN) and edge computing provider founded in 2015, offering services like content delivery, web application firewall (WAF), DDoS protection, and edge compute solutions. Headquartered in Dallas, Texas, it served enterprises and SMBs with a focus on static content delivery and security. The company ceased all operations and liquidated assets in June 2024, following the shutdown of its CDN services in November 2023. Customers included media, gaming, and web application providers before its closure.

History & Notes

NTT Communications leveraged its telecom expertise to deliver CDN services, primarily targeting enterprise clients in Asia and globally. The partnership with EdgeCast enabled features like instant purge and real-time logs, but the service’s reliance on Edgio led to its discontinuation after the 2024 asset sale to Akamai. Some customers may still access archived documentation or support through NTT’s sales channels during the transition period.
StackPath emerged as a consolidator in the CDN market, acquiring MaxCDN (2016) and Highwinds (2017) to bolster its offerings. Its SecureCDN product included WAF and DDoS protection, appealing to media and gaming sectors. Despite raising ~$400M, challenges like management turnover, lack of product focus, and competitive pressures led to its CDN exit in 2023 and full liquidation in 2024. Some customers reported pricing increases and declining support pre-closure.
