[29/06/2019] XSLTEL Downtime Explanation

It all started when my monitoring server (Zabbix) started to complain about SSH service being down on main node. so I logged to iLO console and found a small little message informing me about filesystem corruption and I will need to umount filesystem and do xfs_repair.

So first thing comes to mind is rebooting server into rescue mod, unmount filesystem and xfs_repair. I thought that won't take more than 10 mins to complete.

However in rescue mode everything went as planned and xfs_repair worked with minor complains. but after booting the server I was welcomed with this message again and again :

How to setup Reverse Proxy account on xsl.tel

Hi there,

if you would like to use reverse proxy service to hide your website IP, bypass firewall restrictions (if you have a service running on non-standard port) , cache your static images.

you can always use xsl.tel reverse proxy for this task.

I'm not getting into details on how to order as that should be common sense already I'm going into how to set it up with your domain.

First step after you complete your order you will need to use nameservers provided by xsl.tel with your domain.
Second step login to your control panel received and go to
Domain Setup -> mydomain.com
on this page just set your backend to your real http server/port to something like
http://192.168.2.3:8080

it's as simple as that .
