Routine CNI-disruptive maintenance is planned work that can interrupt traffic on an affected CNI connection. Cloudflare coordinates this work across resilient Cloudflare Network Interconnect (CNI) deployments, including across CNI locations.
For Dataplane v2 connectivity in multi-homed PoPs only:
- Routine maintenance: Minimum one week notice.
- Emergency maintenance: Best-effort notice, which may be less than one week.
- Routine maintenance on redundant devices at the same location will occur on different days.
- Routine maintenance is not rescheduled to accommodate customer schedule preferences.
| CNI deployment | During routine CNI-disruptive maintenance |
|---|---|
| One CNI connection at one location | The connection can be interrupted. |
| Two CNI connections on separate devices at one location | One connection remains in service. |
| Four CNI connections across two coordinated locations, with two connections on separate devices at each location | Three connections remain in service. |
Non-routine maintenance, such as maintenance that affects an entire PoP, can affect all CNI connections at the affected location. For the four-connection deployment with two connections at each of two locations, a full-PoP non-routine event at one location can interrupt two connections, leaving two in service. Cloudflare avoids performing non-routine maintenance at multiple coordinated locations at the same time.
Cloudflare coordinates emergency maintenance across locations where feasible.
