- Surfshark adds thousands of servers to its FastTrack optimization feature
- The technology now spans over 2,000 servers
- VPN collects user feedback for further expansion
It was August 2025 when Surfshark told TechRadar that it would be expanding its custom-built FastTrack technology – its feature designed to optimize VPN traffic routing – and we’re happy 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, it 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 are a user, it is likely that it is also already available in your city; 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.
Instead of simply routing the user through a single virtual private network (VPN) path to connect to a server, FastTrack’s algorithm calculates the actual latency values recorded in its network to identify the fastest route to the specific VPN server.
Specifically, globally distributed probes run speed tests, measure latency, and store the results to determine the best performing route for a user 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 to the VPN server and the traffic follows the available route. With FastTrack, all network nodes are constantly monitored. Something that enables the system to continuously select the optimal connection.
FastTrack update: started with 3 locations last year and now covers more than half of our server network across all continents. Up to 70% faster VPN speeds on macOS. Real-time route optimization, fully automatic. Look for the FastTrack icon in your server list.16 July 2026
Karolis Kaciulis, lead systems engineer at Surfshark, claims that these calculations optimize routes regardless of their geographic location. “For example, if a longer path can actually improve performance due to better conditions because it uses more advanced routers or higher capacity cables, FastTrack will choose that.”
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 almost seems like a natural progression and follows the VPN provider’s announcement in October 2025 of a massive expansion – both in quantity and quality – of its global server network.
Last year, Surfshark actually 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 biggest benefit of FastTrack, but using FastTrack also offers additional benefits, Surfshark claims.
For example, it ensures a significant reduction in routing errors, since one of the key features of Nexus — Surfshark’s routing infrastructure — is precisely its redundancy.
Because Nexus offers multiple routes within the network, if one route encounters a problem, traffic can be automatically rerouted via another available route, helping to prevent disruptions or slowdowns.
Surfshark also claims that FastTrack improves the VPN service in general as it operates on a different data center network than traditional ISPs, which naturally reduces the likelihood of throttling or various network restrictions.
So are there any downsides to this unique technology? Probably the most pressing issue at the moment is that it’s 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’re incorporating user feedback to help determine where to expand next,” a Surfshark spokesperson told TechRadar, raising hopes that new updates are already on the way.
