Sourceforge still works, and is (now) reliable. The awful DevShare malware stuff that Sourceforge started (under new ownership) in 2012 was stopped (under different new ownership) in 2016.
The site is ugly and difficult to navigate. Go there and enter TCL in the search box and see how many clicks you have to do to actually find the project. Then when you click the download button a timer has to run out before the download will start.
Maybe it technically works, but it's a terrible UX.
