Summary
Crucial Web Hosting in conjunction with Cisco Systems have identified a service impacting bug in the current IOS version running on this router. A vendor recommended upgrade has been provided as a resolution and needs to be implemented immediately.
Original Issue Reference
With the introduction of 4-byte ASNs (Autonomous System Numbers), a newly devised method of injecting a specifically crafted prefix into the global route table allows for the BGP process to be reset on older IOS code.

Client Impact
During this maintenance, clients will notice a complete loss of connectivity to their servers on the frontend network (public network). Backend network (private network) connectivity will not be impacted during this maintenance.
While the upgrade duration is scheduled for 1 hour, we only expect between 15-20 minutes of downtime as the routers reload and fully converge. Again, this will not impact the backend network (private network) for client servers.
A notice will also be posted in the portal prior to the maintenance, during the maintenance informing you of the progress, and after with completion details.
If you have any problems with your connection to your services after this maintenance window, or if you have any questions regarding the maintenance at any point, please open a ticket with Technical Support.
We appreciate your patience during this maintenance and welcome any feedback you may have.
