Yesterday afternoon Kenny Freestone of Ancestry.com announced that yesterday evening their tree serivce would be down for about 30 minutes. (See Ancestry Trees Service Will Be Down Tonight) What's notable is not the service interruption but the fact that they told us about it beforehand. When I was at Ancestry I stuck my neck out a couple of times and announced here on these pages a planned outage.
I don't think Ancestry.com was ever opposed to you knowing about planned outages, I just think that prior to their blog, they just had no easy way of informing you. And perhaps because there was no easy way of informing you, product managers weren't in that mode of thinking.
My how times have changed since I started this blog--desparate for candid vendor/market communications. Bravo, Ancestry.com
