Is it only on my side, or others have troubles to use the: http://download.eclipse.org/releases/oxygen/ p2 repository?
My p2 directory is just in a timeout loop so I killed him for time being. A few hours ago I was able to use it happily and just right know I need to install quickly few things :/
Is it under a heavy load, or it's in middle of restructuring? For example, yesterday I noticed the Oxygen2 download was dropped.
It was a temporary outage, @howlger pointed to useful resources: https://status.eclipse.org/ and in case the repository will not even open in the browser then this can be useful as well: https://downforeveryoneorjustme.com/
