It is, but it was reset (again) relatively recently. You may need to contact membership@ to get access.
I just regained my access to matrix.sdf.org after contacting membership, but when I logged into the server I didn't see any of the rooms listed on SDF's page. I've sent another message to membership asking about room access, and will report back here
Hi @rickumali! I'm in matrix too. Here are some links I copied from my session. Look forward to seeing your avatar there.

I believe it is, yes.
Is it necessary to request access to connect to the rooms from my own homeserver?
I don't think this is necessary for public rooms. The sdf matrix lobby is listed as public. I've been able to one-click into a public room on a different server without requesting access.
Wait, SDF has a Matrix server too? How long has that been a thing?
The original invites look to be from Dec 2021 and it was refreshed in Feb 2023 (complete do-over?). All announcements have been coming to my SDF email account from Membership.
