Network outage, Auranhelmi
On Linnankatu near the WTC towers, the fiber optic cable was cut at 12:25 p.m. The preliminary repair schedule is not yet known.
Edit 28.7: The problem was finally solved yesterday 27.7 on the afternoon. New cable is installed, connected and tested. We apologize for the long interruption.
Edit and summary 3.8: So the problem started on 28.6. when fiber optic cables were cut at the construction site of the Linnankatu rope factory. The purpose was to move all fiber optic cables out from under the construction site to a new route. The matter was complicated by the fact that the fiber optic cable placement right purchased by TYS and Ty in 1998 in the operator’s cable duct was marked in its own documents and in the wiring map service as running on the other side of Linnankatu, i.e. not in the construction site area. However, the operator knew the correct route and it went right through the site area, but for some reason this information had not reached all parties. In the demonstration of cable locations ordered by the operator, our fiber optic cable was marked as so-called “cold”. It took some time to first find the cut fiber optic cable and to find common ground between the operator, the contractor and the excavation company to get the replacement fiber optic cable to run along a new route.
Yesterday, 2.8.2023, the speed of the connection to the Auranhelmi was increased from 1 Gbit/s -> 10 Gbit/s. Based on the tests, the connections work normally and the speeds are in accordance with what the 100/1000 Mbit/s ports of the network switch can offer.
