SynEdge is a Luxembourg-based CDN provider with sales offices in the United Kingdom and the Netherlands. The company is a subsidiary of the POST Luxembourg group, a large, semi government-owned mail and telecommunications corporation in Luxembourg. Other related subsidiaries include European Business Reliance Centre (EBRC), Visual Online, Eltrona, Victor Buck Services and InTech.
Based on the network map of SynEdge, we assume they lease (part of) the network of Highwinds, possibly with a few added points-of-presence (PoPs) of their own.
Next to regular static content delivery, SynEdge offers private CDN, dynamic content delivery, frontend optimisation and storage.
ChinaNetCenter is one of the leading Chinese Internet service platform providers that offers both coverage of mainland China and in the rest of the world. ChinaNetCenter was founded in 2000 and was listed on the Shenzhen Stock Exchange in 2009. Its US subsidiary MileWEB was set up in 2012 and tasked with globalising ChinaNetCenter’s CDN services. Global sales operations followed in 2014 and MileWEB was renamed to Quantil.
The company has over 500 ‘CDN nodes’ in mainland China, covering all the major cities. Another 60 of these CDN nodes, what we assume are PoPs, are located in Europe and the United States. Next to CDN services, ChinaNetCenter offers server hosting and rental.
Features or products offered by ChinaNetCenter include the usual, such as download delivery, site acceleration, mobile acceleration and media streaming.
Note that international businesses require an Internet Content Provider (ICP) license to operate their site from China. Most Chinese CDN providers such as ChinaNetCenter and Quantil offer support to clients applying for the ICP license. Mind that without a license, Chinese ISPs are required to restrict access to the website.
