What is the file name of the assignment you are working on?
Practice Lab: Neural Networks for Binary Classification
s172-29-65-130p8888.lab-aws-production.deeplearning.ai’s server IP address could not be found.
Looks like all labs are back now. Thank you very much.

I am able to load those labs without difficulty.
Perhaps it’s a problem with your internet provider.
Did you manage to load the labs?
Yes, thanks for all the help here. So far it is loading fine since I changed my network to use Google’s name server instead of automatic.
I am unable to submit Unsupervised Learning→week 1→practice lab 1
it is giving an error:
multiple times, other labs are successfully grading but not this one. i tried incognito but same issue.
An unexpected error occurred. Please try again later
