Dear customers,

We have planned a maintenance in order to perform an upgrade on one of our voice switches.

There will be two brief moments during which ongoing calls may be dropped: at 23:00 when traffic is moved away from the switch being upgraded (only calls currently running through this switch will be impacted), and between 23:15 and 23:30 when it comes back into service.

Please find all details below:

Start*: 16-06-2026 22:30
End*: 16-06-2026 23:30
Duration: 1 hour
Impacted services: Fixed telephony
Affected Areas**: All areas

Update 16/06/2026 16:55: This maintenance has been postponed. We will update this post when the new window is confirmed.

We apologize for the inconveniences.
