java - Appengine custom domain sometimes redirecting to google.com -

-

i have appengine application written in java gwt frontend.

i have own dns configured, through "domains" in google admin console, point appengine application. configuration have been working 3 years.

starting 3 weeks ago, me , testing users started witness sporadic redirections (302) google.com when typing our domain. nothing related requests appears on appengine log, so, i'm assuming it's not problem related project or configuration in appengine. also, nothing changed in domains (google admin) configuration , dns recently.

what strange, problem occurs 1 time per day (sometimes more) , lasts minutes. doesn't occur @ same time and, when problem occurs, opening in browser or smartphone works fine. after minutes starts work in browser.

anyone have clue on what's going on?

please see google cloud status dashboard additional information on recent issue custom domains.

i not positive whether previous problem occurrences domain caused same problem, though.
