Presently, PPS web services are experiencing intermittent unavailability and/or slow response times. PPS is aware of this issue and our System Programmers are working diligently to correct these issues.
The current anomaly affects our arthurhou server which include the PPS Public site http://pps.gsfc.nasa.gov/ , FTP services, STORM: https://storm.pps.eosdis.nasa.gov/ and THOR (THOR online) , etc.
We hope to have all these services restored to normal as soon as possible and will keep you informed as the situation changes.
We regret any inconvenience that this may cause and kindly appreciate your patience.
