Established Connectivity
AltNet Partners
Several established connectivity operators in the UK (Openreach, Virgin Media, Colt, Vodafone etc.) run their own fibre networks. However, many other alternative network providers (AltNets) are building their own independent networks to provide further competition to the traditional carriers.
These AltNets use fibre-optic cables throughout, have no reliance on legacy copper services and are often more cost-effective than the larger operators.
There are a significant number of UK AltNets operating today with varying levels of maturity. We have engaged with many of them over the last two years to understand their role in building modern, IP-based connectivity solutions for our customers. We can now offer services from 24 AltNet partners! We are unaware of any other network aggregator working with this number of AltNet partners today, and we expect this number to increase over the coming years.
Partner with us
Competitive advantage:
- We can offer fibre-based broadband to a higher percentage of businesses compared to other ISPs that rely on just the Openreach network.
- We can have true carrier diversity both at the physical and logical layers, resulting in better uptime and associated SLAs.
- We can provide value for money. By working with a significantly higher number of fibre providers, we are able to find a good balance between cost and product availability.
- While many ISPs today are considering using AltNets, Flexgrid is ahead of the curve, and our customers are receiving the benefits of this.
