Cannot fetch the index metadata

[glouppe]

It seems the ArgoFloats-index dataset cannot be fetched anymore. Executing the first code snippet of https://argopy.readthedocs.io/en/latest/visualisation.html#trajectories results in a 404 error.

from argopy import IndexFetcher as ArgoIndexFetcher
idx = ArgoIndexFetcher().float([6902745, 6902746]).load()

Indeed, accessing https://erddap.ifremer.fr/erddap/tabledap/ArgoFloats-index.csv results in a 404 error.

Hi @glouppe

Web API can show some downtimes This morning your request seems to work fine You can check the status of argopy online ressources at: https://argopy.statuspage.io/ or in your code with:

argopy.status()

more here: https://argopy.readthedocs.io/en/latest/data_sources.html#status-of-sources

and, by the way, I should recommend you to use the gdac data sources for the index fetcher, it's much more efficient than the default erddap.

Thanks Guillaume! Indeed, everything seems to work now.
