From Larry Berlin, Director of Technical Operations
If this week's Microsoft outage reminded us of anything, it's that no technology company, regardless of its size or resources, is immune to disruption.
Microsoft 365 experienced widespread issues affecting Outlook, portions of Teams, and other connected services. The impact extended beyond Microsoft itself, disrupting third-party applications that depend on its infrastructure.
And that's the part worth paying attention to.
Modern software doesn't operate in isolation. It relies on cloud infrastructure, authentication providers, APIs, and third-party services. When one of those components experiences problems, the effects can extend well beyond the original outage.
For mortgage lenders, that matters. Technology interruptions aren’t just an inconvenience. They can mean delayed disclosures, interrupted workflows, missed deadlines, and frustrated borrowers.
Building for the Unexpected
At Wilqo, we recognize that we can't control the availability of every technology provider we work with. What we can control is how we architect, monitor, and operate Charlie, our Production Optimization Platform.
A few principles guide our approach:
1. Visibility before problems become bigger problems.
Monitoring and alerting are critical to identifying issues quickly. Understanding what's happening across an application and its integrations helps technical teams respond before isolated problems turn into widespread disruptions.
2. Understanding our dependencies.
Integrations are essential to modern mortgage technology, but every integration introduces another potential point of failure. We believe in understanding those dependencies, monitoring their health, and designing workflows that minimize unnecessary disruption when an external service becomes unavailable.
3. Protecting the integrity of the loan.
Availability is important, but so is data integrity. In mortgage lending, an interrupted transaction cannot result in lost information, inconsistent loan data, or uncertainty about what was completed. Reliable systems must account for interruptions and recover in a controlled, predictable manner.
4. Operational readiness matters as much as architecture.
Technology alone doesn't create resilience. Clear escalation procedures, incident response practices, and communication are equally important. When something goes wrong, the speed and discipline of the response can make a significant difference.
Reliability Is an Ongoing Commitment
There's no such thing as a platform that will never experience an outage. Anyone promising otherwise isn't being realistic.
What separates technology providers is how seriously they prepare for disruptions, how quickly they recognize them, and how effectively they recover.
At Wilqo, we're building Charlie with those realities in mind. Our responsibility isn't simply to deliver powerful mortgage technology. It's to help lenders operate with confidence, even in an increasingly interconnected and unpredictable technology environment.
Because when your business depends on technology to keep loans moving, resilience isn't an optional feature.
It's part of the foundation.
