2015-01-29 22:36:38 - Re: January 2015 weather update problems
I started to wonder bit how reliable the weather update process in the server has been. This data is from the new server, starting from September 2013.

I must say that the process has been much stabler than I actually thought, overall in 1.5 years we have missed only 4 weather updates completely.

The times in these statistics are the time when the weather file loading to the server has finished. After that it takes 2-3 minutes to be modified to suit the race areas. So the times shown in the client as the weather timestamp are in average few minutes later than these times.

So if the average time the 04:30 update has arrived to the server is 04:25 then the average time it has been available for clients is perhaps 04:28.

Viva Markku,

It is a lot easier to criticize than do it.
Doing well as this is the case is simply demonstrated by an impeccable record.
Hats off to the WF SOL team.
Sail Fair.

taken by an Italian government site of weather forecast:

PROBLEMA MODELLI: Avviso agli utenti.

Nell'ultima settimana abbiamo avuto diversi problemi con i modelli: sono saltate alcune "corse" inficiando molti servizi, tra cui le mappe vento&mare.
Il problema è dovuto alla quasi saturazione della banda internet dell'NCEP (National Center Environmental Prediction della NOAA), causato da una sempre maggiore richiesta di dati dai vari centri del mondo e sopratutto dal recente aumento di risoluzione del modello globale GFS passato da circa 30 km a circa 13 km di risoluzione. Infatti i file disseminati seppur ad una risoluzione minore (di circa 25 km) pesano circa 4 volte di più dei precedenti (circa 300 MB a file).
Nella segnalazione allegata la NOAA rassicura sul fatto che sono a conoscenza del problema e stanno studiando una soluzione, tra cui un aumento di banda disponibile, previsto per Aprile - Giugno. Fino ad allora faremo del nostro meglio per continuare a garantire il servizio senza interruzioni, scusandoci sin da ora per gli inconvenienti causati e futuri.

"NCEP Central Operations systems -- the NCEP FTP Server (“ftpprd”) , NOMADS and MAG systems, and the recently-implemented MADIS and MRMS applications, are being affected by an Internet capacity issue at the NOAA Network Operations Center. The manifestation of this issue is slow data retrieval from these services. The root cause of the issue is that these dissemination systems utilize the NOAA Internet link and that link has reached saturation, especially at those times of the day when the major models are being disseminated. The slowness has been exacerbated by the recent GFS model upgrade, which gave users access to the new high-resolution dataset and also some of the existing output files increased in size dramatically with the model resolution increase.

The plan to address this Internet capacity issue is for the NOAA NOC to increase the capacity of the NOAA Internet link. This activity is currently in the procurement phase, with an FY15Q3 (April – June) implementation goal. NCEP is working closely with the NOAA NOC to track the progress of this upgrade. In the interim, NCEP is investigating some stop-gap measures that could provide some very limited relief.

We apologize for the impact this has had on our customers. We recognize that the ability to retrieve our products in a timely fashion is very important to our users and I assure you we are working to address the situation.

Becky Alwyn Cosgrove
Chief, NCEP Central Operations, Production Management Branch"

TuziTekwini TIMED Race 2025

Sailonline is delighted to have been invited to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have 13 days and 11 hours to test your skill and decision making after the race opens.
