MODIS/Terra Availability after DOY 166

There don't appear to be any status notifications on the LAADS DAAC main page. https://ladsweb.modaps.eosdis...

500 and 502 Proxy errors for https://ladsweb.modaps.eosdis.nasa.gov/

Has there been a recent nginx configuration change to ladsweb.modaps.eosdis.nasa.gov? As noted in the title we are receiving a high rate of 500 and 502 errors for requests against a range of urls in that domain. Is this related to the investigation for this issue https://forum.earthdata.nasa.gov/vie...

Generating a new token seemed to work. Is there a reason why the previous token (which was generated approx 1 week ago) suddenly began failing? We use these persistent tokens in our production system which is dependent on daily Aqua and Terra downloads, is there a new token expiration strategy which...

Degraded download performance for MODIS products

Since the change in authorization tokens noted here https://ladsweb.modaps.eosdis.nasa.gov/alerts-and-issues/?id=63093 on June 1 we have noted degraded performance for a variety of MODIS products (MOD09CMA and MOD09CMG most notably).
