Summary0003052: Provide reliable web service with solar data in Logbook
DescriptionThe logbook provides solar data. (It's available from the "View" menu in a "Solar Cylce" tear-off, at the "Display" command.) There are three different sources of data that are downloaded periodically by the Logbook, glued together, and drawn on a graph. If any data source fails, the user ends up looking at stale data.

Thing is, the data sources are unreliable. Three data sources come from websites, which aren't too bad though they occasionally fial. The fourth data source comes from an FTP site which is slow and unreliable. I've not been able to find any terms-of-service guarantee (or any other documentation, for that matter) from the data source provider. I imagine that the large number of HRD users frequently hitting the FTP and web sites are not making the site administrators too happy.

We can solve both of these problems by re-publishing the data in our own web service. I propose building a web servre that downloads tihs data a few times a day -- once every eight hours is probably more than often enough. When the data is downloaded successfully, it is retained and made available from a known URL. Maybe the URL is served by a CDN.

The HRD applications are changed to download only from that known URL. This relieves the load on the third-party servers.

It also puts us back in control of our own customer experience. If we can assure that the data is downloaded rapidly and reliably, our customers are happy and we're not left to blame an unknown third-party for a bad user experience.
TagsNo tags attached.

For the moment, I have placed this file at

This was a manual effort. I'll do this manually until I automate it.

Let's go forward with this.

This checkin uses the new URL.

Will we also move the other files to the site? If so, please let know when they're changed and what the new URLs are.

This change moves us away from FTP, but to HTTPS. HTTPS has problems on some OSes because it requires a good TLS configuration. Until we stop supporting downlevel OSes (see Mantis 2757), we'll have to test features like this to see if they work correctly without TLS support in the OS.

When I can automate the file transfer, I’ll pick up the remaining files.
