The details and timeline of the activity are reported below.

Single or multiple outage(s) and duration(s): Single, up to 1 minute.
Service impact: The Enhanced Site Switch (ESS) will keep the service interruption for each user terminal below 1 minute. Although the expected interruption per terminal is single, a limited number of terminals could require a longer period of time to re-acquire the network.
In some circumstances terminals that fail to rejoin this region may switch to another if available.

I would like to take this opportunity to apologise for any inconvenience this activity may cause.
