+
+This script scales the amount of frontpage users up and down, depending on factors such as download time, amount of frontpage users, and our own personal preferences. We add this script to crontab, and it is run every 15 minute. The way this script is configured above, will make bookface automaticly add frontpage users by 25 if the download time is 1.9 secunds or less. If the download time is more than 5.0 seconds, bookface will automaticly remove 50 frontpage users, and by this reduce the amount of frontpage users.
+
+## Task 3
+
+We need to get the download time for bookface the last 24 hours. First, we run this command and get the data in this format(the command and output is for the last 1 hour only):
