147.75.88.62 is the old IP address of the grafana server, moved as part of #3108.

On www I've updated the IP address in /etc/telegraf/telegraf.conf and restarted the service (systemctl restart telegraf.service). Will need to do the same for the other servers connected to grafana.

Updated unencrypted, ci, ci-release and gh-bot.
As an aside, this has triggered a low disk space alert for www in #nodejs-build-infra-alerts on the OpenJS Foundation Slack.
