Poor Download Performance
This was first reported on 2022-04-18 and documented in https://ictjira.alma.cl/browse/AES-52 What we have seen/has been reported is that sometimes downloads are incredibly slow (10s of kB/s) and sometimes the transfer is closed with data missing from the download. Other times we see perfectly reasonable download speeds (~10 MB/s). This was reproducable with a command like the following
wget --no-check-certificate http://almascience.nrao.edu/dataPortal/member.uid___A001_X1358_Xd2.3C286_sci.spw31.cube.I.pbcor.fits
Shortly after this report, the almascience portal was redirected from the production docker swarm to the test-prod docker swarm because it produced better download performance, although still not as good as was expected (10s of MB/s).
