coverage
blood against blackout only lists meetings from public Meeting Guide / TSML / BMLT JSON feeds for A.A., N.A., and C.A. If a city is missing, the local office has not published a feed we can ingest — not that there are no meetings. UK GSO, UKNA, and CAUK locators are not public JSON feeds, so we link to them instead of scraping.
official locators
If a public JSON feed is missing, use the official locator for that fellowship instead of assuming there are no meetings.
Intergroups can publish the same Meeting Guide JSON this app already ingests: add <link rel="alternate" type="application/json" title="Meetings Feed"> on the office website.
