1 hour down time tonight
 

We will be undergoing UNIX framework maintenance for approximately one hour tonight. This will start at 8 p.m. Pacific time. We anticipate 1 hour or less for going dark. Sorry for the inconvenience, but that is sometimes when it has to be done to keep us operating smoothly.

was this to patch against the heartbleed openSSL exploit?

I have chromebleed(heartbleed vulnerability detector) installed and it's not throwing any red flags.
