The Google 'Blogger' facility has been down since early yesterday afternoon New York time. From what I could tell they had made a system change earlier in the week, and it led to a system crash, that took some time and archive retrievals in order to restore.
These things do happen. At one time I managed portions of a major communications network that stretched across the US and to over fifty countries. Major software upgrades were always the sort of thing that spoke to the quality of one's processes and system testing. And even then, things do happen.
Regular updates tonight.
