  1. Log into the AWS Console in us-east-1 using the jcsda-noaa account.
  2. Navigate to the EC2 Instance dashboard.
  3. Click the checkbox next to "skylab.jcsda.org" or "experiments.jcsda.org" depending on which site is down. 
  4. Click the drop down arrow next to "Instance state" in the top bar and select "Reboot instance". This might take some time to stop and start. Once it says running again, verify the website is reachable and try to connect to the instance via ssh as the ubuntu user. If those fail, then you will need to stop/start the instance. That will change the public IP address so more steps will need to be taken in order to update with the new IP. Proceed to steps 5-X.
  5. Under "Instance state" click on "Stop instance" to shut it down. If this takes longer then a few minutes, do a "Force stop instance".
  6. Start the instance again, click "Instance state" and "Start instance". After it is back running, try to connect to the instance via ssh as the ubuntu user.
  7. Copy the new  “Public IPv4 address” and navigate to the Route 53 dashboard. Click "Hosted zones" then "jcsda.org". Scroll down to experiments.jcsda.org or skylab.jcsda.org and click "Edit record". Paste the new IP where the old one is and click "Save".
  8. Try loading the web page. If it still does not load, try with a different browser. If that does not load then you will need to restart services, so proceed with steps 9-X.
  9. Log back into the instance as user ubuntu via ssh. 

  10. Restart the following services and run:

    Code Block
    sudo systemctl restart nginx.service
sudo systemclt daemon-reload
sudo systemclt restart voila.service


  11. Verify the website is back up and running.
