Board » General Discussion » Global Challenge downtime - how to cope with server outages

	Redress is applied after the finish. The finish time is corrected after a race committee decides what time was lost. This happens IRL, for example when a racer deviates to help a boat in distress. I do not like the options where the boats are held or moved. As Piero says, the wx moves on. Tactics are based on predicted wx, so changing the boat positions will not work. The admin folk do a great job already and have a lot to do. We should be able to set up race committees that do not require much time from the current admin, most positions could surely be filled with volunteers. It would also help to have people on the race committee who know how this works IRL. Kevin

	Lou, no need to be sorry. I think it's really good to have discussions on what to do on server problems. Naturally we do always our best to prevent any problems but when you face running a game which basically requires 24/7 uptime for weeks, you have to be realistic that downtime happens. When there are any issues with the game the admins naturally try to do the "best effort" so that the issue is resolved and the effect to the players is a minimal as possible. Discussions like this help us to think what are the best possible actions in the problem situations and also how players view them (instead of us just guessing). However, there is always the limiting technical side of the things. With the current sol sailing server we can do: - Stop the whole server, so that all boats freeze - Remove future dc's for a given time or a race (or all of them) - Restart a race However, without developing new features the server in my knowledge the following can't be done: - Freeze just one race - Freeze the weather model, so even if the whole server is freezed weather will go on - Give time allowance to any boat (redress) - Move the boats from where they are (except to race start) I believe freezing just one race and the time allowance would not be very hard to implement but tampering with the weather model I can't see happening as it is very deep in the server (and client). Moving boats is somewhere there between.

	Thank you all for your input so far, there is realy some good thoughts in this and like Markku noted, we like to know not guess what you all feel works best. As far as technical options its like Markku noted, we can stop all races but not individual ones at this time. Nor redress a single boat during a race. Tampering with weather in short or long term messes up the long term planning for a race. Esp in long races where you wan't to be is everything. That said if we come up with a good idea that can really help us out the technical problems should be able to be solved. I am a ex-admin of SOL who joins in from time to time.

	Hi, Just on the fact thats is impossible to freeze one race, from my point of view thats no point, if there is a server problem, this problem would be the same for all races, so it's almost logic that all races are freezed as soon as possible. Ciao, Lou

	Unfortunately it was found out that freezing all games proved to be very difficult as well. The sailing engine tries always to make up for the time it has been down (but there is an upper limit on the time it tries). The reasoning in freezing different races is that the races can be in very different situations so the same action is not necessarily the best for all of them.

	Just an idea, is it possible that a router, at the moment of a shutdown, calculates an ETA , with the weather forecast of that moment, for all boats in competition, and that you make a ranking with that result, and then restart from a central postion, with the average of the results make a final ranking. Probably a lot of work, but a honest solution, a machine takes the decision. Ciao, Lou

	Certainly a interesting scenario when you choose to abandon a race and would like to calculate the more true result. Restarting from a single point in a race like the Golbal Race does take away a lot of tactics and has a big impact as a solution itself. It would be nice to keep the spread out fleet in this case alive. I am a ex-admin of SOL who joins in from time to time.

Round Greenland 2024

Just as Skip Novak was embarking for Kamchatsky, Amyr Klink also quietly slipped his Antarctica moorings and by now Paratii 2 has reached Reykjavik, where he invites you to join him on Leg 5 of our High Latitudes Series, a full 3650nm circumnavigation of Greenland. The course is clockwise round, so down the North Atlantic to Cape Farewell, then up the Davis Strait into Baffin Bay and on into the Arctic Ocean proper, where, hopefully and certainly virtually, Paratii 2’s special ice-breaker features will get us thorough the summer ice out onto the Greenland Sea and back to Reykjavik. Stay warm!

San Francisco to Ushuaia 2024

After a superlong RTW-leg3 (27 days), we have had a month to recover, and maintain our boat, in order to continue our around the world race. Leg 4, even longer than the previous, takes us from California to the world's southernmost city Ushuaia. No waypoints, even "the Ditch" is an option, but maybe a bit too much of a treat. With 6300 nm to go, the estimated duration of this race 29 days. This course is also the August edition of our ocean race championship.
