Power BI is a great and powerful tool. However, the Power BI service should be more reliable and resilient as it isn't available all the time. In the past few months it has been down quite a few times and often for more than a day affecting many corporations, users and day-to-day processes which I think isn't acceptable.
We (all Northern Europe tenants) had 3 outages in the past 48 days. This resulted in about 27 hours of downtime for our Power BI reports which is nearly 2.5% of the total time ... this is a far cry from the promised 99.9% availability (and that is excluding the major issue of 11 Dec which affected our reports partly but which took more than a week to get resolved). I don't think this is acceptable and Microsoft should address this.
So please vote to request a reliable and resilient 24/7 service from Microsoft!
In addition it would be good if Microsoft would be quicker to update their Power BI support page when there is an outage and also to give an estimate of time when to expect an issue to be resolved. It would also help as part of our communication to our users to give an explanation of why the outage happened or what the root cause is.
Based on our own experiences (tentant in North Europe) and of the wider Power BI community I compiled the following Power BI outage list:
Note that the above dates and times are based on entries made on the Power BI Community site and therefore only give an indication of the outage. The three issues from 4 Dec to 6 Dec might all relate to the same issue but is hard to tell.
