Hello, Thanks for the follow-up. The SL-6.x update URL's all timed out starting last Tuesday, 8/18. We hit several different mirrors. After investigating from our side, we found that our LBL security monitoring blocked the SL-6 server ip. I'm cc'ing our Security person who can describe why that happened. The updates are now working.
