The HostSlim network

HostSlim has completely built up its own network in recent years. This gives us complete control over all aspects that take place in our data center. This allows us to manage the service from start to finish.

Our own network (AS207083) is connected to several world wild peering partners and the Amsterdam Internet Exchange. In addition, our two data centers are interconnected via a physical fiber optic connection.

In addition, HostSlim has DDoS protection on its network to guarantee good protection and uptime for our customers.

Redundant Network
The fiber optic paths from HostSlim to our peering partners in Nikhef Amsterdam, among others, have been purchased from various suppliers via long-term contracts, which means that a long-term underlying SLA and other agreements apply. We use at least two fiber optic paths which are physically separated over the entire route, so that both paths can never be interrupted at once during excavation work or other problems. In addition, HSDC1 and HSDC2 both have their own routers and routing engines running redundantly. This means that if a router in one of the locations fails, the other location will automatically take over all routes without interruption.

HostSlim uses DWDM technology to send light of different wavelengths over the same fibers between its own data center locations. This technique makes it possible to grow the capacity of the connection as the need grows. To cope with the loss of one of the fiber optic connections, HostSlim uses a routing protocol that detects the loss of a connection and automatically switches to another route. This switch happens so quickly that connections are not affected.

Peering our network
A connection between the HostSlim network and the network of another Internet Service Provider can be established in two ways. You can exchange traffic directly with ISPs in the vicinity, without the intervention of a third party. This is called peering. Such an exchange takes place in Internet Exchanges (IX). In our case AMS-IX. We apply a so-called open peering policy. We peer on these Internet Exchanges with every party that registers with us. We use Transit partners for global networks for ISPs. These are parties that connect us to networks that are not present on the same internet exchanges as HostSlim. We have specially selected our peering partners based on capacity, routes and quality of their network. We have at least two transit partners for each physical connection. For this reason, there is always redundancy. Should a transit partner fail for any reason, the other partner will automatically take over the routes.

IP protocol
HostSlim supports both IPv4 and IPv6 and also offers IP addresses in both protocols.
