We have fixed networking issue with IS in https://rt.admin.canonical.com/Ticket/Display.html?id=163604 and currently it looks like some charmhub.io related issue. Reported here, but maybe you want to collaborate IS to fix collaboration page! :-D

P.S. normally reply time below one second, but slow in about 10% cases.
