Outage and vulnerability notifications.

Hey like the title says I'm looking for a way to keep up with outages and vulnerabilities. I mostly used r/sysadmin to alert me to things, but given everything I don't want to go to reddit if I don't have to.

If I can have my preference I just want one point to check at least until the numbers build up here and it becomes the go to place for that info. Anybody know of anything?
