WINDOW: Thursday 19th April 22:00 - 23:59 GMT
ESTIMATED DOWNTIME: 5 MINUTES
NETWORK IMPACT: PARTIAL
DESCRIPTION:

JTAC (Juniper Technical Assistance Center) have informed our network provider (Goscomb) that a new software release will most likely solve their current VRRP releated issues. As such, they are scheduling the above emergency maintenance period to upgrade each of their 2 core routers (one in IPH and one in THE).

The routers will be upgraded one at a time and will result in some network insta bility (due to the fact that VRRP is currently not working as expected). Each router upgrade is expected to last approximately 5 minutes at the most.

A snapshot of the current router OS and config will be taken prior to each upgrade and should any part of the process fail these snapshots will be restored.

We apologise for the short notice of this maintenance work.

Maintenance Window : 4th April 00:00 - 06:30

Extreme have recently made some upgrade recommendations following a complete internal review of our interconnection provider’s network at the start of the year. They have after careful consideration advised them that they should bring our software into line with the latest version for XOS capable devices in order to remove the possibility of the platform being hit by some service affecting bugs and also to allow for the future deployment of improved features.

The code has already been validated in our provider’s configuration by Extreme and they have performed testing in a lab environment.

- IPHouse (Expected Downtime 5 minutes)
This work maybe service effecting; both nodes within our cluster may go offline during this period. Our Linux server in Meridian gate will not be effected.
