week 2 and week 3 practice labs not working

week 4 Practice Lab: Decision Trees s172-29-101-98p8888.lab-aws-production.deeplearning.ai’s server IP address could not be found.

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.
