Dear Client,

We would like to notify you of upcoming emergency cooling maintenance activities that will affect services in our Rotterdam datacenter. The emergency cooling maintenance has been scheduled for January 19, 2026 through January 22, 2026.

Location: Rotterdam, Netherlands

Schedule: Start time: January 19, 2026, 7:00 UTC End time: January 22, 2026, 16:00 UTC Planned impact: Reduced redundancy (see below for details)

Reason for this maintenance: We will be performing a cooling maintenance on our two cooling pumps of both A and B line to ensure continued performance, efficiency, and reliability of the system. We will adjust the start-up procedure so that both pumps start simultaneously

Expected impact: During the maintenance window the redundancy of the cooling system will be reduced

Support: Our support department will be open during the maintenance. More details about how you can contact our support can be found here: Support You can find maintenance updates and the current situation at i3D.net - Status

Dear Client,

We would like to notify you of upcoming network maintenance activities that will affect your services in our US datacenters. The network maintenances have been scheduled for January 26, 2026

Location: United States

Schedule: Start time: January 26, 2026, 00:00 UTC End time: January 26, 2026, 02:00 UTC

Planned impact: No impact (see below for details)

Reason for this maintenance: We will be deploying granular anti-DDoS filters at our external network edge. This will ensure we can filter out common network attacks without affecting legitimate use of the protocols being used for these attacks. DNS and NTP are examples of DDoS attack vectors that frequently see legitimate use. Deployment will occur in a carefully phased approach, so we expect that in the unlikely case of issues, we can detect quickly and revert prior to impact.

No Impact: No impact is expected for this maintenance. This has been tested and implemented on other sites without resulting any impact.

Support: Our support department will be open during the maintenance. More details about how you can contact our support can be found here: Support

Dear Client,

We would like to notify you of upcoming network maintenance activities that will affect services in our Singapore datacenter. The network maintenance has been scheduled for January 27, 2026.

Location: Singapore, Singapore

Schedule: Start time: January 27, 2026, 22:00 UTC End time: January 28, 2026, 03:00 UTC Planned impact: Reduced Redundancy (see below for details)

Reason for this maintenance: The maintenance is required to address difference in configuration behaviour in newer software releases. This will prevent potential issues and ensure we can maintain stability.

Expected impact: Reduced Redundancy: As the activity will be executed one aggregation switch at a time, there is no impact expected. During this maintenance there will be reduced redundancy.

Support: Our support department will be open during the maintenance. More details about how you can contact our support can be found here: https://www.i3d.net/support/

Date

Time (UTC)

Maintenance Work

January 29, 2026

06:00 - 16:00

The maintenance will be carried out on the generator and transformer breakers. Once the work is completed, there will be reduced redundancy. During transformer breaker maintenance, Powerhouse 1 will operate on generators. During the generator breaker maintenance, there will be reduced redundancy.

February 2 & 3, 2026

06:00 - 16:00

Maintenance will be performed on the UPS1 breakers. While this maintenance is in progress, generators will run in parallel with the power grid to provide continuity in the event of a grid failure, as UPS protection will not be available during this period.

February 4

06:00 - 16:00

Breaker maintenance on UPS2 will take place. Impacted customers will be notified separately..

February 5

06:00 - 16:00

Power impact may occur due to switching activities in the main panels.

February 6 & 9

06:00 - 16:00

Switching activities will take place in the main power distribution board in Powerhouse 1.

Planned impact: Reduced redundancy (see below for details)

Reason for this maintenance: Mandatory maintenance to ensure the safety, reliability and correct operation of our main power infrastructure.

Expected impact: Reduced redundancy: During the maintenance window, parts of the power infrastructure will be worked on one at a time which may temporarily reduce redundancy. Power will remain available throughout the maintenance and customers who may be affected will be notified separately.
