Note from my hardware provider. This could impact all the shared hosting and VM's provided by myself, but hopefully there won't be any disruption


Telehouse North 2 Core: 01:00:00 AM - 02:00:00 AM
Reason and impact:


We'll be introducing an alternative form of OOB access via serial over IP devices in addition to the current management port based OOB access. No impact is expected, although we will be performing operations on the routing engines as such connectivity traversing through this core PoP is at risk.

Rollback plan:
In case of any issues, we will disconnect the newly connected devices and roll back the configuration changes if any.

Telehouse North 2 Distribution Switches (QFX 5100): 02:00:00 AM - 04:00:00 AM
Reason and impact:


In response to a recently discovered service affecting software bug we'll be implementing a service release of JunOS - Juniper Operating System across this distribution switches/routers. This is service affecting and will require a reboot of those switches one by one. The impact will vary depending on how you're connected, if at all.

If your connection to this switch is resilient (Dedicated Servers at THN2 location, traversing from core through distribution to Top of Rack) you theoretically shouldn't be affected, however, in our lab test, we have sometimes, seen a blip of approximately 5 minutes per reboot, approximately 10 minutes total within the window.

If your connection to this switch is not resilient you'll see approximately 30 minutes downtime within the window. This includes LINX LON2 connectivity as well as a small number of services directly fed of the Distribution Switch.

Rollback Plan:
Although we have extensively tested this new release in the lab, if there are any issues observed, we will back the current, known working release of the software.
