why can't I open the link of jetson resources??? any problem with NVIDIA's web server??

Hi,all,
when i open the link for jetson TX2 resources,

i.e. the following URL:
developer.nvidia.com/embedded/jetpack

the browser shows the following error:

504 gateway timeout
     nginx/1.13.3

what‘s wrong with it?
is there any problem with the website server of
NVIDIA??

please help me with this~~

Hi, I just checked, and it’s up for me without problems. Are you able to reach the site now? If not, can you try http://downforeveryoneorjustme.com or http://www.isitdownrightnow.com/ ?

I tried it also and it is up for me.
