There was a trouble in international bulletin exchange over GTS, which caused significant loss of data in the GISC cache around 12UTC to 18UTC on 8 Wed January. That includes all GTS messages including coarse-resolution GRIB1 bulletins from JMA GSM.
RTH Tokyo was receiving a huge number of a single bulletin repeatedly, and went beyond its capacity. Delivery to GISC cache system had to be turned off during the recovery operation.
I'm afraid there is no plan to re-deliver the lost data to GISC cache, as it is classified as WIS Part B, i.e. the service in best effort basis. Operation-critical users are advised to subscribe to the WIS Part A service, for example dedicated-bandwidth GTS for neighbouring NMHSs, or JMBSC for commercial weather enterprises.
High-resolution GSM data service was not affected since it is coming through different channel.
I apologise all users for inconveniences. All delivery is now working normally.
You are very politely not saying where "a huge number of a single bulletin" came from. I hope not from DCPC EUMETSAT.
