Connection timeout

I am unable to connect to realms, it is definitely not my wifi nor other issue! My friend who use a different wifi cant connect to the world as well. Realm was still working ytd night but today after a long wait, it just show connection timeout!!! I have been spending 1 hours+ to follow all the step including restart realm and restart my computer! Please advise on this and get back to me asap!
