Lab 3 error - AWS is currently experiencing networking

While submitting lab 3, got error and then refreshed vocareum page, I am getting below error.

AWS is currently experiencing networking issues which has led to increased error rates on our platform. AWS is working to identify the root cause and mitigate impact. Please try later

Getting the same error on lab 2. Now the error becomes: All servers for this assignment are permanently offline. If you believe this to be in error, please contact Vocareum support.

AWS is currently having technical problems. Hopefully they will fix it soon.

Tried today, submitted the ab again successfully
