Just loggen on to my WordPress installation and notice that there were four updates to carry out. Did the two plugins okay, then clicked on the Twenty Eleven Theme Update to 1.5 and after finished pressed the 'return to updates' page and was met with this message...
"Briefly unavailable for scheduled maintenance. Check back in a minute."
That lasted for over 10 minutes but it is now all displaying correctly. Can anyone comment as to why this happened, the Theme update only took a few seconds and I don't have a huge amount on the site. I have my WordPress hosted on UK2.Net in London and logged on to the server after a couple of minutes but could not see any issues.
Just interested in understanding what may have been going on.
