We are still having availability issues on XWiki. XWiki was down for way too much time today. We are unsatisfied with the current level of service.
One of the reasons is that XWiki is having more and more success both in number of wikis and in page views.
We will be working hard in the month of February to work on a better platform for XWiki adapted to the number of users we have. It will take some time to set this up but once it is done it should be a high availability service.
Thanks for your support
