Guys, you are not about stable update in general, you are about mirror servers specifically, it’s already a specific discussion in general topic, please open specific thread for your special need.
Or even better: to search this forum, old Manjaro forum, Internet.
Most probably - 99% possibility - other people met you problems, so the your tasks transforms to learn to search you want - to find special words which was used by people before you. It will be so much appreciated to see unique and complex issues only. Take a bit efforts to get an answers to you: try to figure out by yourself, if no luck, then post.
Try to increase your mental skills by 
with a problem by 
(yourself) and if you realized that it is hard enough (do not be fooled by laziness), than post and 
(community) will come into play. If we will waste community efforts to simple things, than Manjaro development as whole project will be slower, but if we will efforts to solve our problems with ourselves a bit more, than we will a bit free Manjaro team resources and they can use it to learn new (year they also need to learn to provide better service for us) and to implement it for us all. Let’s try a bit harder to solve our own issues we have.
We have a biggest resource on the 
ever: all info posted by people around the Globe. To learn how to search - to be a 
of knowledge and to 
our problems
