Week 4 Assignment is not opening

I have been trying to open week 4 programming assignment but it is not opening. It keeps showing waiting for coursera.org. I am working with a stable internet connection. Kindly help.

There’s nothing Deep Learning AI can do about Coursera’s web service. Maybe they’re having a technical problem.

i just tried loading the C5 W4 A1 notebook, it took only a few seconds.
