Switching business internet without downtime
Switching providers goes badly for one reason almost every time: the old circuit is cancelled before the new one is proven.
Overlap the two circuits on purpose
Plan to pay for both connections for one to four weeks. That overlap is the cheapest insurance you will ever buy: it lets the new circuit be installed, tested under real load and left running alongside the old one before anything is cancelled. Businesses that skip the overlap to save a few hundred dollars routinely lose more than that in one bad afternoon.
Check your exit terms before you sign anything new
Read the termination clause of your current agreement first: notice period, early termination fee, auto-renewal date and how notice must be delivered. Many commercial contracts auto-renew unless cancelled in a specific window. Line the new install date up with that window so you are not paying a penalty and a new bill at once.
Port phone numbers early and separately
Number porting runs on its own clock and is the most common cause of a messy cutover. Start the port request as soon as the new service is ordered, keep the old lines active until the port completes, and confirm that main line, fax and any published numbers are all included. Never cancel the losing carrier before the port is finished — cancelling can release the number.
Cut over in a quiet window, with a rollback
- Pick the lowest-traffic hour for your business, not the installer's convenience.
- Test payments, phones, cameras, cloud apps and guest Wi-Fi from the new circuit before switching the default route.
- Keep the old circuit physically connected so you can roll back in minutes.
- Re-point anything with a hard-coded IP: cameras, VPN endpoints, on-site servers, alarm and payment terminals.
- Confirm remote monitoring and alerting still report correctly after the change.
- Cancel the old service only after a full business week on the new one.
