In our organisation (located in Melbourne, Australia) we have multiple tenants of SharePoint Online. Since last few weeks we have noticed that one tenant is responding very slow. All other tenants are working fine. Other office 365 services are also working fine. We are trying to identify cause of this problem if it is on our side. It is defiantly not related to our network because other tenants are working fine. Also, because when we try to access our SP site from outside network, it is still slow. We are facing this issue only during 9 am-5 pm. We have already raised it to Microsoft. I need to know: 1. Is there anything else we can do except raising this issue to Microsoft? 2. Is there anyone else in the same region who is currently facing same issue?
