M365 Weekly Newsletter
☁️What’s on my mind
My sincere sympathies go to Rackspace and its IT professionals. They were sweating last weekend. I know the feeling because I have tried to get an Exchange server up and running at inhuman hours in the past.
Do you know the story? Their hosted Exchange service was down all weekend and even on Monday, it’s not working as it should. At the time of writing this, the security incident is not yet officially being talked about, they have just hinted that this is probably it.
The latest info from their side suggests that the’ve been a victim to ransomware attack.
And that, of course, immediately raises a few questions. Given that hosted Exchange is much closer to Exchange on-premises than Exchange Online in sense of architecture, I wonder if there is any room left for hosted Exchange players.
Not because Microsoft is in their way and stopping them, but because Microsoft simply has the needed human resources to prevent such attacks. But let’s not jinx the whole thing.
Well, after all, Exchange Online runs at the vendor itself, which has all the source code readily available, while Rackspace has hosted Exchange, which depends on Microsoft’s whim as to when it will release patches for the Exchange server. That’s the curse of hosted and on-premises (not only) Exchange servers.
Given that Rackspace in light of the events recommends migrating to Microsoft 365 or Exchange Online, answers are probably at hand:
If you offer your own hosted Exchange, it’s just a question of when you’re going to move your customers to the Microsoft cloud: before you’re hacked or afterwards.
Have a really great day.
