There will be a brief period of downtime tonight (3/19/2018), around 8:15 PM. It will likely last about 30-45 minutes as we restart our servers to apply kernel updates to them.
Edit (8:20 PM): We have started. See you on the flip side!
Edit (8:40 PM): We have rebooted a majority of our public services, they should be coming up soon. Public mirrors are still to come.
Edit (8:50 PM): Our MySQL database did not start correctly, so we have started that now. We are also in the process of rebooting our public software mirrors host.
Edit (9:00 PM): Restarting our servers is fully complete, thanks for your patience!
