I was using it on Friday. My friend couldn't connect and I had trouble jumping into voice chat. I closed the client and was able to log in 10 minutes later. Overall I only noticed an issue for about 15-20 minutes. Having just read the post mortem I'm pretty impressed with their service and operations.
They don't have a posted outage for Saturday, but I noticed issues with it on Saturday evening/night I believe. I'm wondering if it was related to the issues that they included in the post-mortem.
Very possible you saw a slight interruption around 11:30PST for around 10 minutes until we found and decommissioned the host that experienced this problem. We generally don't update status until we can verify impact/source, we see tons of limited outages from ISPs misbehaving.
