For customers who require assistance outside of normal business hours, options may include access to emergency support or after-hours services, depending on the specific plan. It is essential to review the service level agreements associated with your account. Customers might find that certain critical issues can be addressed even outside of regular support hours, while non-urgent matters could be deferred until the next business day. Additionally, XO Communications may provide online resources, such as a knowledge base or troubleshooting guides, which can be useful for resolving common issues independently.
