Today (June 26 2019) attempts from our university (York University in Toronto, Canada) to access anything within domain r-project.org fails. I checked with a colleague at Purdue and he had no problem, suggesting there may be something amiss locally or in whatever DNS servers we go to.

Result from Brave browser:

This site can’t be reached www.r-project.org’s server IP address could not be found. Try:

Henryk's problem was resolved by the message from phiver that R-forge would be down for maintenance in early June. It's not clear to me that our problem is the same? Is there a place other than r-project.org to check for scheduled maintenance of the site?
