Not only a problem related to uptime reports, what's more problematic is that it potentially can break sites when they don't go into maintenance mode for the full update period. Both during and after updates, especially for ecommerce sites etc. Those things is kind of connected, and it's a long time pending issue: https://wp-umbrella.canny.io/features-request/p/activate-maintenance-mode-automatically-on-updates

Absolutely — I fully agree with your suggestion, and it's an important one.

Automatically pausing uptime monitoring during WPU plugin updates would significantly reduce false-positive downtime alerts and improve the accuracy of incident reporting. These alerts can be misleading and cause unnecessary concern or manual investigation, especially when the downtime is expected and temporary.
