We are performing routine router upgrades overnight, including a "rolling" LNS upgrade. This will cause customer lines on the 'Witless' set of LNSs to drop and reconnect when thy are on is updated. We will be doing one LNS a night and the work starts from 1AM. The 'Witless' LNSs manage our FTTP estate as well as some 80M FTTC lines.
