List of mirror URLs for IERS download
See original GitHub issueBoth of the USNO hosts (maia.usno.navy.mil, toshi.nofs.navy.mil) for retrieving the IERS Bulletin A dataset are flaky. Instead of a primary URL specified by the configuration setting utils.iers.iers_auto_url
and mirror URL by utils.iers.iers_auto_url_mirror
, I suggest a single list of URLs.
Here is what I propose for backward compatibility:
- Understand both
iers_auto_url
andiers_auto_url_mirror
to be either a string or a list of strings. - Construct the list of URLs to try by concatenating all of the URLs from
iers_auto_url
andiers_auto_url_mirror
and removing duplicates. - Deprecate the
iers_auto_url_mirror
configuration setting for removal in a future release.
Here is a possible default URL list:

I’m not sure if this is the right thread, but there’s a big red warning on both
http://maia.usno.navy.mil/
andhttp://toshi.nofs.navy.mil/
saying that they will be down for maintenance from Oct. 24 2019 until April 30 2020 (6 months!). Is the community already aware of this?@pllim, no, it’s still really flaky. Our project (growth-astro/growth-too-marshal) has to download the IERS files in its CI tests, and even with the https URL, it’s failing more often than it is succeeding. I think that we really do need a list of fallback URLs. Also, astroplan needs to be able to use the fallbacks.
