NOS nowCOAST Informational Message
3:30 PM EST Tuesday, Dec. 1, 2020

SUBJECT:   The NWS National Centers for Environmental Prediction (NCEP) is
seeking public comments through December 18, 2020, on the management of
user access of the NCEP hosted Web Services including NOAA's
nowcoast.noaa.gov. In addition, NCEP is holding a virtual public forum to
discuss mitigation options on December 8, 2020, at 2 pm EST.

Background:

FROM: Brian Gross Acting Director, NWS/NCEP
As demand for data continues to grow across NCEP websites including
nowcoast.noaa.gov, NCEP is  proposing to put new limits into place to
safeguard their web services.

The frequency of how often these websites are accessed by the public has
created limitations and infrastructure constraints. To add new or upgraded
streams of data, there has to be a reduction in the number of connections
into our system. The mitigation will reduce the strain on our
infrastructure, ensuring a more robust level of service for all users.

 For example, a possible mitigation would lower the limit of the number of
connections to 60 per minute for a given user accessing any of the websites
below. This would be a cumulative limit for any type of data request across
any website.  A "head" request will count towards the limit the same as a
"get" request. Websites affected, both ftp and https, would include
nowcoast.noaa.gov.

NWS/NCEP will be holding a virtual public forum to discuss this and other
mitigation options on December 8, 2020, at 2 pm EST.  One can register for
the meeting at:
