On Thursday, November 12, 2026, Microsoft 365 experienced a widespread service degradation. Outlook, Teams, and other Microsoft 365 services had connectivity problems for much of the afternoon, and Microsoft’s own status page showed the issue was still ongoing. Azure, Microsoft’s broader cloud platform, was not reporting a similar outage.
For a lot of businesses, the surprising part wasn’t that email was hard to open. It was that other things broke too.
A website can be online. An application can still load. And the functions that make them useful can still fail. If your site or your software sends email through Microsoft — a contact form, an appointment confirmation, a password reset, a patient or customer notification — those messages depend on Microsoft being available. When it isn’t, the site looks fine and the mail never goes out.
That’s exactly what happened to one of our clients today. They reached out because their website had stopped emailing. The site itself was up. The email function was not, because it ran through Microsoft.
This is what redundancy means.
Redundancy is not a technical buzzword. It means a critical function has more than one way to work. If there is only one path, and that path is down, the function is down. If there is a backup path, the business can keep moving.
Think about outgoing email. If the only way your website can send a message is through one Microsoft mailbox, then a Microsoft outage takes that function with it. A second email service, a queue that holds messages and sends them when the first path is back, or an automatic failover to a backup provider, is redundancy. The same idea applies to logins, payments, appointment reminders, and any other function your business cannot afford to lose.
You don’t need to duplicate everything you use. You do need to know which functions are mission-critical, and make sure those are not sitting on a single point of failure.
A few practical places to start:
- Make a short list of the functions that would hurt immediately if they stopped: email from the website or app, appointment or order notifications, staff communication, file access, payments.
- For each one, ask a simple question: if this provider is down, is there another way for this to work?
- Don’t judge health by the homepage alone. A site can be up while the mail, login, or form behind it is not.
- In healthcare and other regulated or high-stakes industries, a missed message is not just inconvenient. Plan for that from the start.
This is the work we do at Helbling Digital Media. We consult on and manage the workflows behind your websites and applications, and we help you put redundancy in place on the platforms your business depends on. We do this in healthcare and across many other industries, because when a system is critical to the business, it needs more than one way to keep working.
