Network Outage Notice

2017-01-25 17:00, JT7A: All apartments at Jämeräntaival 7 A are currently without a network connection. There is a major cable cut within the building due to ongoing renovation works.

2017-01-25 19:30, JT7A: Currently we cannot give an ETA for repair but most probably it will take days due to scale of the problem, all cables were cut. We are working on temporary wireless Internet service.

2017-01-26 20:55, JT7A: A new fiber into the building has been build and we will start restoring services tomorrow morning. The plan to provide a temporary service has been scrapped, it's faster to rebuild normal access connections.

Trinet, the Otaniemi area campus network, was founded in 1986. Today it provides Internet access to all Otaniemi located student apartments and dormitories owned by the Aalto University Student Union (AYY) and the Foundation for Student Housing in the Helsinki Region (HOAS). The network covers about 2500 student households and is connected to Funet, the Finnish national research and education network. This allows the use of academic network services in addition to a fast and reliable general Internet connectivity.

Most apartments and dormitory rooms have 1 Gbps access connectivity and almost all buildings have at least a 10 Gbps uplink to the backbone. The 1 Gbps upgrade project, which originally started in 2010, will be completed after building renovations at Jämeräntaival 10 and 11.

Trinet has 2 * 10 Gbps redundant connections to the Internet via Funet. Trinet uplinks are connected to Funet in Espoo and Helsinki.

Along with the wired service, the AYY wireless network is available in sauna, party and meeting facilities (see current coverage). It provides secure encrypted access via eduroam authentication (essid "eduroam") or unencrypted access via the AYY open access network (essid "tupsu"). In addition, an experimental IPv6-only open access service (essid "tupsuv6only") and an IPv6-only eduroam network (essid "eduroamv6only") are available.

The network provides both IPv4 and IPv6 connectivity. IPv4 multicast is supported throughout the network and IPv6 multicast within the apartment buildings upgraded to 1 Gbps access connectivity. IPTV is the major application for multicast, and is offered via AYY IPTV services. Users may also receive multicast streams from the Internet.

Elisa Cable TV and AYY IPTV

Cable TV service is provided by Elisa. However, the old AYY IPTV service is also available.


Please check the instructions on how to configure your network settings before connecting the Trinet network.
