Connection to oceandata.sci.gsfc.nasa.gov was impossible between :
April 9 14h47 UTC and April 10 10hUTC
April 10 20hUTC and April 11 10h UTC
April 11 19hUTC and April 12 10h UTC
Outside of these time periods everything is fine.
Do you experience some problem on your side ?
Is our IP address (220.127.116.11) blocked ?
Thank you for your help,
Yes, that IP was tripping an automated temporary block due to excessive 404 errors in a short period of time. Seems there were a few files that where requested multiple times, despite the initial attempt getting a 404. Are you assuming filenames and querying for them with the expectation that they will exist? If so, you probably shouldn't. As of today, there are still a number of 404 errors from that IP, but they have not exceeded the threshold...yet.
If it does, you may be temporarily blocked again.
Sorry for non answering earlier, I was out of my office the last two weeks.
We have 404 errors when we try to access to a directory that does not exists yet. This error occurs every day between 0h UTC and typically 03h UTC because the day number directory has not yet been created on your archive. But as we only wget the content of this directory every 10 mn, this makes about 30 ERROR 404 messages (15 for L1A, 15 for L2 SST). But the main source of error occurs when processing MODIS L1A in NRT with SeaDAS : we build the name of attitude or ephemeris file from the date of the granule (this also holds for ozone or meteo files), and we try to donwload these ancillary files but in most cases there are not yet available on the archive.
We will correct our scripts to check the file presence on your archive before trying to wget them.
We thank you for pointing out these 404 errors, and we apologize for our uncontrolled wget commands.
