We just received notice from Serverius team for upcoming maintenance for transit network.
Start: 2017-07-12 22:00:00 CEST
End: 2017-07-12 23:00:00 CEST
Reason: This year we were faced with a lot of maintenances at the fiber network in the Netherlands. During those maintenances our L2 transport service was affected and our clients had outages. Also, the total amount of traffic in our Transport network is always increasing, just like the expectations of our clients to this service. To avoid the outages in the future with relation to planned or emergency maintenances of our fiber suppliers, and to increase the amount of ports and total capacity, we have built a totally new Transport network. This network is based on the newest Huawei CloudEngine hardware and has fully redundant fiber channels. It's done like fully redundant and fully independent of main Serverius IP transit network.
Expected Outage: At this step of the implementation, we should migrate all existing L2 vlans connections between SDC1 and SDC2 to the new Transport network. Expected outage is up to 30 seconds for reconnections.
