We'll be performing routine overnight software upgrades on our pool of LNSs and BGP routers, starting Monday 23 February. One LNS will be done per night, and this involves moving lines between the LNSs and upgrading when lines have been moved off. Customers may see a PPP drop and reconnect in the early hours of the morning as this work is carried out.
Upgrades to our BGP routers will also happen overnight but should have little to no impact.
BT have a series of planned work that involves them replacing cable bundles that include our hostlinks - our interconnects into BT's network. We're not sure when these will take place, but will happen between 00:30 and 02:00 and will happen over three nights. This will cause 'blips' for many customers - lines will drop and reconnect within seconds or a couple of minutes.
We would usually be able mitigate any disruption by cleaning moving our traffic off the affected links. However, at the moment BT have not specified which link and the date that this work will happen. Thanks BT!
