Blogspot is again experiencing problems - we are investigating.
Update, 8PM: We have restored all of Blog*Spot, save one of our filers. This means that some blogs will still be unpublishable and inaccessible. Our engineers are continuing to work on this problem.
Update, 11PM: Blog*Spot servers are restarting now and connecting with the filer. All blogs should be publishable and accessible within the next 20–30 minutes.
[So how has everyone else’s weekend been? —Pete]
