[NOTICE] Major hardware upgrade (system memory)
The available RAM on the server running five simulator-regions (one region per simulator) has been increased from 8GB to 32GB (DDR3) and performance has been radically improved as a result. Even for OpenSim, which is quite heavy on memory, this is a lot.
Ocean Grid is still operating on an old Intel® Core™ i5-2400 CPU @ 3.10GHz x 4 processor with 1TB hard drive space. However, it is more than capable of running a Linux server.
[RESOLVED] 2DO.pm events down
The 2DO.pm service is no longer available, as happened to its predecessor HYPEvents. We hope that this will be resolved somehow.
Resolved by a server reset following an enquiry.
[COMPLETE] Added optional TLS ("SSL") login port 9002
It is now possible and recommended to log into Ocean Grid securely using TLS (often wrongly known by the name of its now defunct predecessor SSL). The OpenSim software does not directly allow this, although simulators can communicate with the ROBUST server and the viewer by secure ports (for example the 1280x1280 test region Rheged on Ocean Grid). However, it is possibly to achieve secure logins using a reverse proxy like Nginx, which is what was used here. The port that has been used is 9002. The information on the web site has been updated accordingly. The insecure port 8002 is still available for the reasons explained below. Both work fine. Please use the secure port if you can.
A blog post detailing how this was done can now be found will appear on Starflower Bracken's blog in the fullness of time. We have used Let's Encrypt certificates and these are accepted by the viewer. If you get an SSL connect error, please read the next paragraph because it DOES work and it's not a problem with the grid:
Issue: there is a viewer bug [FIRE-24068, SV-2392] in all older viewers that prevents the Grid selector from allowing https:// prefixes, which is annoying. This means, for the present if you use such viewers, that you may need to manually edit grids.user.xml or grids.xml depending on which viewer you use. Consequently this isn't yet very accessible except to users of older viewers with unless they have considerable technical competence. For now, This means that the old insecure HTTP port 8002 will remain in use as well but this is now under review.

[INFO] Ocean Grid back online
The grid has been down since 2020 as a result of a server hardware fault that has now been rectified. Hooray, we are back.
[RESOLVED] 2DO.pm Hypergrid Events (no service)
As of 15 March 2020 the service is back online, presumably after a server restart.
There are currently no events on 2DO.pm since 2 March 2020 when it seems that the service went down. As a result, the events boards are blank in the welcome area on Annwfn and the whole system doesn't work. This is a problem because, to be effective, such services need to be relied on by people. We've seen it before with Hypergrid listing services. So far no response has been forthcoming from them but hopefully the problem will be temporary.
The 2DO.pm events on our login screen have been removed and a script added to restore them automatically as and when there are any to show.
Note: it is possible to fork this service, as it was itself a fork of HYPEvents.
