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.
EdgeCast operates 25 data centers across seven countries, with points of presence (PoPs) in North America, Europe, Asia, and other regions, following its acquisition by Parler Cloud Technologies.

The architecture is designed for low-latency video streaming and edge computing, with strong global coverage but limited public details on specific PoP counts or capacity.
