CPDLC and Iridium issues

The Pacific: General Aviation & Questions - PPRuNe Forums - www.pprune.org
Hello,

Been seeing some NOTAMs from NZZO, stating they aren't using CPDLC VIA Iridium at the moment. Messages are getting delayed, so you could get a "Climb FL390" hours later. NZ started it, and now Oakland Oceanic following suit. Some have reported that one message was delivered 23.5 hours later...
