- Surfshark adds thousands of servers to its FastTrack optimization feature
- The technology now spans more than 2,000 servers.
- The VPN is collecting user feedback for further expansion
It was August 2025 when Surfshark told TechRadar that it would be expanding its custom FastTrack technology, its feature designed to optimize the routing of VPN traffic, and we’re happy to confirm that it has kept its word.
In a recent post shared on X, Surfshark announced that it has updated 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 are a user, it is likely already available in your city as well; just look for the FastTrack icon in the server list to find out.
A comprehensive network update
Fast track 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) route to connect to a server, FastTrack’s algorithm calculates the actual latency values detected within your 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 to the VPN server and traffic follows the available route. With FastTrack, all nodes on the network are constantly monitored. Something that allows the system to continually 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. Route optimization in real time, fully automatic. Look for the FastTrack icon in your server list.July 16, 2026
Karolis Kaciulis, Lead Systems Engineer at Surfshark, says these calculations optimize routes regardless of their geographic location. “For example, if a longer route can actually improve performance due to better conditions, using 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 over 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 increase.
The expansion seems almost a natural progression and follows the VPN provider’s October 2025 announcement of a massive expansion, both in quantity and quality, of its global server network.
Last year, Surfshark launched another innovative self-healing VPN tool, Everlink. The feature aims to ensure connection stability even in the event of serious failures 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 guarantees a significant reduction in routing errors, since one of the key features of Nexus (Surfshark’s routing infrastructure) is precisely its redundancy.
In fact, as Nexus offers multiple routes within the network, if one route encounters a problem, traffic can be automatically rerouted via another available route, thus helping to avoid interruptions or slowdowns.
Surfshark also claims that FastTrack improves the overall VPN service as it operates on a different data center network than traditional ISPs, which naturally reduces the likelihood of throttling or various network throttling.
So are there any downsides to this unique technology? Probably the most pressing issue currently is that it is only available on the Surfshark page. VPN app for Mac and iOS platforms. These limitations have already led some online users to request an Android version as well.
“We’re plugging user feedback to help determine where to expand next,” a Surfshark spokesperson told TechRadar, fueling hopes that new updates are already on the way.
