As a matter of pure competitive intelligence gathering (i.e. I do not mean this as a rhetorical question), which providers list peering issues on their portal?  Particularly when they might be a bit more of an ongoing nature vs. a concrete outage?

Unfortunately, many issues don't appear (deliberately?) as network events on their portal.
