Dark fiber maintenances of our supplier “Eurofiber” PA-326002 and PA-824003

Dear Customer,

You are receiving this message as an advance notice because our dark fiber suppliers “Eurofiber” will do two Service-Affecting maintenances PA-326002 and PA-824003.

Location = Dronten, NL
Service Type = Dark fiber

PA- 824003 :

Start: 2020-06-11 00:00:00 CEST
End: 2020-06-11 06:00:00 CEST
Duration: 6 hours.


Start: 2020-06-16 00:00:00 CEST
End: 2020-06-16 06:00:00 CEST
Duration: 6 hours.

Reason:  Due to reconstruction work carried out by the local authorities. Relined is obliged to relocate a section of her network. This action will result in a temporary interruption of the service.

This activity will impact the following dark fiber circuits:
SDC1, Dronten < – > SDC2, Meppel

Expected Outage: Is expected downtime of DWDM channels from the SDC1, Dronten to the SDC2, Meppel only. None 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 rebuild routing tables.

We apologize in advance for any inconvenience this might cause.

ASn of Serverius is listed in Microsoft SNDS blacklist

Dear client,

Microsoft Outlook/Hotmail has added all Serverius prefixes to the Microsoft SNDS blacklist. Therefore IP’s which are hosted under the Serverius ASN AS50673 cannot send email to outlook.com and Hotmail.

In the past days, we reached out to Microsoft countless times with very little success. We have escalated where we could, including the relevant governmental institutions.

Unfortunately, Microsoft did not give us any warning, nor information upfront that could prepare us for this situation. To this date, we have not received any proof of malicious activity from our network or any details that could help to resolve this issue. Therefore it’s unclear why our ASN is added to their blacklist.

We will keep pushing Microsoft and any other contacts that could help us to get in contact with the relevant people. There is, unfortunately, no estimate on the time to resolve the issue. When there is news, we will inform you on this page.

Serverius Coronavirus measures

Dear Serverius users,

Yesterday evening, on March 15th, the Dutch government imposed far-reaching measures on everyone in the Netherlands to combat the coronavirus. Their advice to everyone is to stay indoors and to avoid contact with other people as much as possible. Schools, bars, churches, and all non-critical government departments are all closed with immediate effect. These measures will remain effective until April 6th. Our industry has been identified as “crucial” by the government, and therefore we have a great responsibility to perform under any circumstance. We will take our responsibility towards our customers and their users, by doing everything we can to keep the service operating normally.

The Corona situation has a direct effect on all commercial companies in the Netherlands, including Serverius. As a result of this, Serverius will change its staffing schemas to prevent further spreading of the coronavirus, to minimize the risk of illness among our employees and our data center visitors. Starting today, most Serverius engineers will work from home. A different shift schedule of the on-site support department will be used. We will provide the best possible service to our clients with as few on-site staff as possible between 9:00 – 17:00. We sincerely ask you to consider the importance of all remote hands requests, as well as your understanding when some requests may take longer than you have come to expect from us. Urgent matters can be expedited with on-call requests. Our sincere apologies for this, but we assume that you understand this situation of force majeure.

The data center environment and our networks are monitored and operated as usual. In case of emergency, all engineers are available and on-site in a matter of minutes. All supporting staff (finance, admin, etc.) will operate like usual.

We ask all our clients with personal data center access not to visit the data center until April 6th (this is a preliminary date, subject to change). Only in case of an extreme need which cannot be delayed, you will be allowed to visit the data center. Please announce your visit upfront and refrain from visiting our locations between 09:00 – 17:00, to minimize contact. The visitor flex-working spots (coffee corners) will be closed. inside the datacenter offices it’s not allowed to “hang around”, waiting you should do outside in your car. Without extreme need, you are not allowed to try to contact our engineers to assist you. If physical assistance is really needed, please avoid close contact. A distance of 3 meters should be kept whenever possible.

In the upcoming weeks, new information will be shared through our normal communication channels.

Black building test + transformer maintenance SDC1

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 / Generator tests and maintenance grid transformer
Start: 04.03.2020 7:30 CET (March 4th 2020, Amsterdam time)
End: 04.03.2020 9:30 CET
Expected duration: 2 hours
Service interruption: none expected

Reason: Black building test combined with maintenance works on the transformer.

Please note that, during this test the normal grid power will not be available for period of approximately 20 seconds and the UPS systems 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 main power grid provider will do maintenance on the transformer. 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. 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
