When you have issues with the NCEP NOMADS server you should use this
address - <a class="moz-txt-link-abbreviated" href="mailto:ncep.pmb.dataflow@noaa.gov">ncep.pmb.dataflow@noaa.gov</a> - as we don't always monitor
these user forums. <br>
<br>
On 8/22 a change was made to the OpenDAP server to limit the number
of connections a user can make within a given time period. This was
done after a few users were able to bring the GDS server to a
standstill due to over requests. This change appears to have
affected many users negatively. Once you reach that threshold you a
blocked for a short period and then released, causing your
permission error. We will be upping that threshold number today,
hopefully this will allow all connections that are not malicious to
get through. If you are still seeing problems overnight please let
us know.<br>
