When I entered the Twitter home page to publish my blog update status in my twitter page, I was greeted with a nice banner from Twitter, which says Twitter is over capacity. Too many tweets, please wait a moment and try again.
Even though, I could not publish my tweets, I was very much impressed with their banner which showed a big whale is being carried by twitter icon birds. This can be underscored as a very good way of presenting things when your online service is unable to serve user requests.
Have look at the article which tells about backing up and restoration of blog posts in Blogger Platform.
