Planned maintenance – Brussels DC (PDUs replacement)
Planned8:00 PM – 8:00 PMUTC

  • Dear Customers, dear Partners,

     

    As part of our ongoing efforts to improve our infrastructure, we will replace all power distribution units (PDUs) in our Brussels DC.

     

    The maintenance will take place from 18 November at 9:00 PM to 19 November at 6:00 AM.

     

    As all our racks have redundant power feeds, no service impact is expected from the PDU replacement. However, two switchovers will take place on our Proximus FTTO infrastructure, each causing a service interruption of a few minutes for the affected connections.

    Thank you for your understanding.

     

    Best regards,
    The Sewan Technical Team
