Add outage notification guideline for Global Services

[jmaxmarno]

Added a guideline for notifying WIS2 centres about outages exceeding 4 hours.

Thanks Max. I think we also need to indicate that this notification follows the WIS2 Monitoring Event Specification. @amilan17 should be able to give you a reference to where this new spec will appear in the WIS2 Manual. I think it's likely to be APPENDIX G: WIS2 MONITORING EVENTS.

Note discussion scheduled for ET-W2IT on 11-MAY-2026: which types of events should Global Services be publishing and when. PR wmo-im/wis2-monitoring-events#28 WMEM: add more types and remove data.subtype proposes to add code-list for event type controlled vocab.

From ET-W2IT meeting 11-MAY-2026

ET-WISOP have a separate discussion (see Issue wmo-im/wis2-operation#49) about whether or not a Global Service anticipating an outage should directly create a WIS2 Monitoring Event message, or create a JIRA ticket that will prompt a Global Monitor to automatically generate the message.

ET-W2IT agree that the JIRA-based procedure seems more streamlined as there's no mechanism for a Global Service to directly raise a WME message.

Consequently, the Technical Regulation needs to be updated to state the requirement to raise a JIRA ticket according to a "maintenance" template (details of the template are as yet undefined - but are also not necessary to include in the Techical Regulation).

@jmaxmarno - the text you've added is almost what's needed. I'm going to merge your change and then create a new PR with text mentioning JIRA.

Given change in approach, the proposed text is good.
