Over the next few days we expect to upgrade a number of internal routers - this is part of ongoing work to improve the way we handle DoS attacks in future.
Some work was started tonight, we expect to do more over the next few days.
Some more work this morning - trying to keep any disruption to a minimum.
Some of the updates over the weekend may mean some broadband graphs lose the first few hours of the day.
As part of this work we are doing some further work as described in this post: https://aastatus.net/2180
