Black building test + 2N power upgrade maintenance SDC1[Finished]

Dear Customer,

You are receiving this message as an advance notice of a black building test

Location =Datacenter 1, Dronten, NL (SDC1)
Service Type = Grid / Generators test and maintenance

Start: 06.12.2023 7:00 CET (Amsterdam time)
End: 06.12.2023 9:00 CET
Expected duration: 2 hours

Reason: Black building test combined with works for the 2N power upgrade.

Please note that, during this test the normal grid power will not be available for a period of approximately 20 seconds and the UPS-feeds will take over. Therefore no colocation power will be affected, your equipment and services will not be affected.

During this black building test we will also perform maintenance. The new power divider will be connected to the main power grid. Performing this work on the same time as the yearly black building test will save us another similar maintenance window later on this year.

All activities will be conducted under the direct supervision of Serverius and its external suppliers Elinex Power Solutions and E-tec Power Management. Approximately 30 minutes before the test commences, another reminder that the test is due to start will be sent. After the test and maintenance is finished the noc website noc.serverius.net will be updated that all work is performed.

Because a lot of engineers will be available during this black building test, we would like to ask you NOT to visit the datacenter during this maintenance window. Of course you are allowed to access your hardware but please visit the datacenter ONLY when you really need to. FYI: during this maintenance window the engineers will not communicate to users but updates will be communicated at http://noc.serverius.net

If you have any questions let me know at support@serverius.net

Kind regards, Alfred van den Berg

Dark fiber maintenance of our supplier “Eurofiber” KA-285002

Dear Customer,

Our dark fiber supplier ”Eurofiber” will do a Service-Affecting maintenance KA-285002.

Location: Serverius DC1, Dronten – GlobalSwitch, Amsterdam
Service Type: Dark fiber, DWDM channels

Start: November 23, 2023 – 00:00:00 CET
End: November 23, 2023 – 06:00:00 CET
Duration: 6 hours.

Reason: Final recovery is required to complete repairs on a section of the Eurofiber network that was temporarily repaired in the past to restore traffic during an outage.

This activity will impact the following dark fiber circuits: Serverius DC1, Dronten, NL <-> GlobalSwitch, Amsterdam, NL

Expected Outage: is expected downtime of DWDM channels from Serverius DC1, Dronten to GlobalSwitch, Amsterdam only. No expected outage for IP transit service, other dark fibers will automatically take over the data traffic, but there is a small chance for high latency and short time packet loss in the time of rebuilding routing tables.
