+#RestartSec=5
+
+# IMPORTANT!
+# If you use a database file (not server), then you will need to disable the
+# DynamicUser setting, and manually create the UNIX user and group specified
+# below, to ensure the file is accessible across multiple invocations of the
+# service.
+DynamicUser=true
+
+# You may prefer to use a different user or group name on your system.
+User=speedtest
+Group=speedtest
+
+
+# The following options will work for all configurations, but are not the
+# most secure, so you are advised to customise them as described below:
+
+# If NOT using socket activation, or if using socket activation AND
+# connecting to an external database server (MySQL, postgres) via TCP:
+RestrictAddressFamilies=AF_INET AF_INET6
+
+# If connecting to an external database via unix domain sockets (MySQL
+# default to this mode of operation):
+RestrictAddressFamilies=AF_UNIX
+
+# If using 'none', 'memory', or 'bolt' database types, and socket activation
+# then the process will not need to bind to any new sockets, so we can remove
+# the earlier AF_UNIX option again.  In systemd versions before 249 this is
+# the only way to say "Restrict the use of all address families":
+RestrictAddressFamilies=AF_UNIX
+RestrictAddressFamilies=~AF_UNIX
+# ...in systemd version 249 and later, we can instead use the much clearer:
+#RestrictAddressFamilies=none
+
+# The following options are available (in systemd v247) to restrict the
+# actions of the speedtest server for reasons of increased security.
+
+# As a whole, the purpose of these are to provide an additional layer of
+# security by mitigating any unknown security vulnerabilities which may exist
+# in speedtest or in the libraries, tools and operating system components
+# which it relies upon.
+
+# IMPORTANT!
+# The following line must be customised to your individual requirements.
+# e.g. if using the 'bolt' in-process database type:
+ReadWritePaths=/usr/local/var/speedtest
+
+# Makes created files group-readable, but inaccessible by others
+UMask=027
+
+# Many of the following options are desribed in the systemd.resource-control(5)
+# manual page.
+
+# The following may be useful in your environment:
+#IPAddressDeny=
+#IPAddressAllow=
+#IPAccounting=true
+#IPIngressFilterPath=
+#SocketBindAllow=
+
+# If your system doesn't support all of the features below (e.g. because of
+# the use of a version of systemd older than 247), you may need to comment-out
+# some of the following lines.
+
+# n.b. It may be possible to further restrict speedtest, but this is a good
+# start, and will guard against many potential zero-day vulnerabilities.

         While in state 1, you can only add test points, you cannot change the test settings. When you're done, use selectServer(callback) to select the test point with the lowest ping. This is asynchronous, when it's done, it will call your callback function and move to state 2. Calling setSelectedServer(server) will manually select a server and move to state 2.
     - 2: test point selected, ready to start the test. Use start() to begin, this will move to state 3
     - 3: test running. Here, your onupdate event calback will be called periodically, with data coming from the worker about speed and progress. A data object will be passed to your onupdate function, with the following items:
