Dear All,
As of this morning's 12Z flight it appears that we have solved the Dar
problem. For some reason they were no longer inserting NNNN between
sections and we coached them into inserting it.
So thanks to all for assisting. It took us a bit over 6 weeks to solve
this so I am hopeful that you will come up with a better problem
resolution procedure.
Cheers
Dick

I will contact individual centres with respect to the switching problems identified. Based on the latest available routeing catalogues I have found some inconsistencies in some individual centres. In this case it appears that the delivery problem is more likely to be at the source with only part A of the TEMP report USTN01 HDTA being delivered but not the other parts U(K,L,E)TN01 HDTA.

Depending on the available NMC contacts at Dar Es Salaam with RTH Nairobi and the urgency of the matter a direct phone call appears to be appropriate after repeated attempts by other means of communication.

Any in-depth investigation to the source of the problem would still be handled by the responsible RTH Focal Point together with other RTH/MTN centres to which the responsible RTH is directly or indirectly connected to as the operational centres are normally data centres not manned by professional staff outside office hours. All chains of routeing tables should be examined by the RTH Focal Points. In this case it would be:

I agree with Peiliang that Focal Points for National Centres should also be made available at WMO web site. I believe most RTH/MTN centres would have some sort of informal list of contacts in their region for internal operational use. The matter now is to have a formal list of contacts nominated by the PRs and the continuous effort to update the list.

> When a problem occurs, it is suggested to report the problem to all the links (the NMC, concened RTH and MTN centers) of the distribution at the same time. So that, the concerned centers can make check at their own side, and share the progress and results. In this way, even if we have the contact point for one center on leave, it is still possible to get response from its upstream or downstream links(or centers). This would be helpful to get to the bottom of the problem and have it fixed in time.

> And, at WMO web site (http://www.wmo.int/pages/prog/www/ois/RTHFocalPts/RTHzones_en.html), we now already have the contacts for RTHs. To get in touch with the concerned NMC during a problem investigation, it is also suggested to publish the contact points for NMCs on this page. So we need to re-habilitate the RTH focal-points, as we agreed at the recent MG meeting. And it seems a list of GTS operation focal-points at NC level would be necessary. If we could get feedback directly from Dar es Salaam, the whole story would be different.
