@neeshu , I was responding to the OPs post.
By the way, it's possible to have no issues for years and then suddenly start having them due to more things than just maintenance or planned outages.
Sorry for the service issues. While similar, this sounds like a separate issue so I moved your posts to a new thread. Outages can be caused by a number of different reasons and if it should occur again in the future, you can contact us here or Social Media, where we can provide current available information. Please let us know anytime you need assistance.
