What It Is

SLIX (Salt Lake Internet eXchange) is a neutral, open Internet Exchange Point (IXP) in Salt Lake City, Utah, founded and operated by XMission in 2011. It is not positioned as a traditional CDN; instead, it enables ISPs, CDNs, cloud providers, and enterprise networks to exchange traffic through direct peering, reducing reliance on upstream transit.

Core Capabilities

SLIX supports IPv4, IPv6, and BGPv4. Participants need to have an ASN and connect via a compatible Ethernet port. Its network spans five data centers along the Wasatch Front, rather than operating as a single-facility exchange point. Peak traffic exceeds 1Tbps, with dozens of connected peers. The site also notes access to major content and cloud networks such as Amazon, Google, Microsoft, Cloudflare, and Utah Education Network. In terms of features, SLIX provides route servers and collectors to simplify peering and traffic monitoring, along with 24/7 member support.

Pricing and Billing

SLIX uses port/exchange-access pricing rather than the traffic- or bandwidth-package billing commonly seen with CDNs. Available port options include 1Gb, 10Gb, 40Gb, and 100Gb, with average pricing around USD 500-3000 per month, negotiable based on specific requirements. There is no contract requirement and no installation fee, but customers need to provide their own SFP or purchase one from SLIX.

Pros and Cons

The main advantage is clear network performance optimization for Utah and surrounding regions: SLIX can help reduce latency, improve redundancy, optimize routing efficiency, and lower transit costs. Its pricing is reasonably transparent, and port options are flexible. The downside is that it does not provide CDN product features such as web caching, global edge nodes, WAF, DDoS scrubbing, or edge computing. Access also requires an ASN, BGP, and network operations capability, so it is not suitable for ordinary website owners to use directly.

Best Fit and Access from China

SLIX is best suited for ISPs, CDNs, cloud providers, education networks, and large enterprise networks looking to establish peering in the Salt Lake City area. The site does not specify access from mainland China or payment methods, nor does it mention China-based nodes or ICP filing. If the goal is to accelerate websites in mainland China, local CDN providers such as Alibaba Cloud CDN, Tencent Cloud CDN, and Wangsu Science & Technology should be considered first. For global website acceleration, traditional CDNs such as Cloudflare, Akamai, and Fastly are more relevant comparisons.
