Hello @user_0406d3 Thank you for reaching out to our forums for help with the upcoming network maintenance. This work is happening across all of our areas to improve our network to support upgrading speeds and services. During the process you may experience intermittent service issues, but we are unable to see the specifics of how long an interruption may happen. Based on customers I have worked with in other areas, they experienced slower network speeds for several hours, others found lost connections throughout the day and some even reported no issues at all. I'm sorry I don't have a better expectation to set since the impact has varied for so many. You can always check here to check your area for known interruptions. The Xfinity app can is also easy to check for area issues and will give you the latest as far as expected time frames for resolution or work completion.
