: It's not a bug. Because PBE is a testing server, we have maintenance every weekday. This runs for an approximate of 2 hours during which the server is down and cannot be played on. It happens every weekday at around the same time. As much as you may hate it, this maintenance is necessary for Riot to add, remove, or change content, as well as fix bugs. It will not stop. It has been going on like this for more than 5 years and won't be changing. [Surrenderat20](http://www.surrenderat20.net/search/label/PBE/) makes patch notes for every PBE patch. It's considered wise to stay in the loop using this website, so that one knows what needs to be tested.
But on normal servers i never seen that
