The global Zoom outage on April 16, 2025, which halted video calls, webinars, and Zoom Calendar access across North America, was a stark reminder of DNS’s critical role in modern business. A misconfiguration, likely tied to registrar issues, brought Zoom to its knees, but this vulnerability extends far beyond tech giants. Any organization—be it a Silicon Valley startup or a venture capital firm—can face catastrophic disruptions when DNS is mishandled.
Well-intentioned web developers often make changes that seem routine but end up breaking critical systems like email. At Hybridge, we advocate that all DNS changes, no matter how small, should be entrusted to professionals to ensure uninterrupted operations.
Consider a common scenario: a web developer, tasked with migrating a client’s website to a new hosting platform, follows the host’s instructions to update nameservers. On Monday, they log into the domain registrar and swap the nameservers to point to the new host, expecting a seamless transition. By Tuesday, the website is live, but the client’s email—hosted on a separate provider like Google Workspace or Office 365—stops working entirely. Unbeknownst to the developer, the original nameservers included MX records directing email traffic; the new ones don’t. Employees can’t send or receive messages, clients grow frustrated, and critical emails bounce and are lost. Hours pass before the web developer mentions he changed DNS, costing time, money, and trust. This is just one example of how DNS missteps, however well-intentioned, can spiral into chaos for businesses relying on seamless communication.
Hybridge’s approach eliminates these risks through expert DNS management. Our proprietary DNS platform boasts redundancy across two providers on two continents, delivering uptime that exceeds even Cloudflare’s track record over the last decade, ensuring your domains remain accessible no matter what. For email reliability, we use DMARCian for nearly all our clients, meticulously monitoring email deliverability to guarantee that messages from approved platforms reach their destinations without fail. Whether it’s preventing nameserver errors, configuring MX records, or resolving complex zone file issues, Hybridge’s professionals handle every DNS change with precision.
If you are still using your registrar’s “free” DNS or letting your web developer have direct access to your DNS, please call or email us.
