Important Notice Regarding Upcoming Network Maintenance Activity

We are writing to inform you of upcoming required network maintenance activity related to a forced facility relocation impacting certain services in and through the Sacramento area. 

Zayo is required to complete this relocation within a fixed timeframe that cannot be extended. To meet this deadline, we are executing an accelerated migration of network systems and associated services into a new facility. 

Given the scale of this work, the impending deadline, and the coordination required across active services, maintenance activities will need occur during daytime hours rather than standard overnight maintenance windows. 

We recognize that this approach is not typical and will cause disruption to your operations. Given the constraints of this relocation, this is the only viable way to complete the work in a controlled manner while reducing the risk of longer and less predictable service disruptions. 

What To Expect 

Over the coming days, you may receive an emergency maintenance notification that includes the date and time of scheduled daytime work that will impact your services as part of this facility’s relocation. Once scheduled, maintenance timing will not be adjustable due to the required sequencing of this work. 

It is our expectation to provide as much advance notice as possible for each maintenance activity. However, there will be instances where notice is shorter than standard intervals. 

During this period: 

• You will experience service interruption or degradation during maintenance activities 

• In some cases, impact durations may be longer than typical maintenance windows 

• In certain situations, work will need to proceed with minimal advance notice 

Our goal is to minimize the duration of any impact and restore services as quickly and safely as possible. Updates will be provided throughout the work, including estimated restoration timing when available. 

This work is being sequenced carefully, but variability should be expected given the complexity of the migration and dependencies involved. 

Zayo has dedicated engineering, field, and vendor teams actively engaged in this effort. Work is being carried out in a structured sequence to maintain as much service continuity as possible while progressing the relocation.

We understand the critical role these services play in your operations and are focused on completing this work with as little disruption as possible.
