- Surfshark adds thousands of servers to its FastTrack optimisation feature
- The technology now spans over 2.000 servers
- The VPN is gathering user feedback for further expansion
It was August 2025 when Surfshark told TechRadar that it would expand its custom-built FastTrack technology — its feature designed to optimise VPN traffic routing — and we’re pleased to confirm that it has kept its word.
In a recent post shared on X, Surfshark announced that it has upgraded its infrastructure, making the technology available on more than half of its servers across all continents.
In practical terms, this means that FastTrack, which promises speeds 70% faster than even the best VPNs, is now available on around 50% of its current network of 4.500 servers. If you’re a user, chances are it’s already available in your city too; just check for the FastTrack icon in the server list to find out.
A wide network upgrade
FastTrack is an optimization feature that Surfshark uses on part of its server network.
Rather than simply routing the user via a single virtual private network (VPN) path to connect to a server, FastTrack’s algorithm calculates the actual latency values detected within its network to identify the fastest route to that specific VPN server.
Specifically, globally distributed probes run speed tests, measure latency, and save the results to determine the best-performing route for a user located in a specific country who needs to access a specific VPN location.
The system differs from traditional systems, where a server establishes a direct connection with the VPN server, and traffic follows the available route. With FastTrack, all network nodes are constantly monitored. Something that allows the system to continuously select the optimal connection.

Karolis Kaciulis, Leading System Engineer at Surfshark, claims these calculations optimise routes regardless of their geographical location. “For example, if a longer path can actually enhance performance due to better conditions, as it uses more advanced routers or higher-capacity cables, FastTrack will select it.”
While the feature was initially limited to just three servers (Sydney, Seattle, and Vancouver), Surfshark has now converted more than 2.000 of its exit nodes to FastTrack, allowing users to connect to a much wider range of new servers that can benefit from the same speed boost.
The expansion seems almost a natural progression and follows the VPN provider’s announcement in October 2025 regarding a massive expansion — both in quantity and quality — of its global server network.
Last year, Surfshark indeed released another innovative self-healing VPN tool, Everlink. The feature aims to ensure connection stability even in the event of serious malfunctions or service interruptions.
More than speed
Of course, speed is obviously the main advantage of FastTrack, but using FastTrack also brings additional benefits, Surfshark claims.
For example, it ensures a significant reduction in routing errors, as one of the key features of Nexus — Surfshark’s routing infrastructure — is precisely its redundancy.
Indeed, as Nexus offers multiple routes within the network, if one route encounters a problem, traffic can be automatically redirected via another available route, thereby helping to prevent interruptions or slowdowns.
Surfshark also claims that FastTrack improves the VPN service overall, as it operates on a different data center network from traditional ISPs, naturally reducing the likelihood of throttling or various network limitations.
So, are there any drawbacks to this unique technology? Probably the most pressing issue currently is that it is only available on Surfshark’s VPN app for Mac and iOS platforms. These limitations have already prompted some users online to call for an Android version as well.
“We are connecting user feedback to help determine where to expand next,” a Surfshark spokesperson told TechRadar, fuelling hopes that new updates are already on the way.
