Office 365 Admin Centers Slow

We are experiencing the same sluggish admin interfaces here. It has been the case for the entire year we've been using o365, across multiple machines and with a fast net connection. It must be pretty embarrassing to be a major cloud provider who doesn't have the infrastructure to provide even an acceptable user experience to admins. I imagine it's also a huge disincentive for partners and service resellers as they're the ones who will receive the support calls but will not be able to take any action. At the moment this issue is preventing us from expanding into o365; we're staying on prem until it's sorted or we find a decent competitor.
