There are a few services I provide to the public for anyone to use, and a few services I run for a limited group of users (mainly friends and family). If you know me and are interested in access to one of the internal services, contact me and I’ll get you hooked up.
Most of the services are hosted in Germany, although some are (additionally) hosted in USA or Canada for redundancy. Maintenance is generally done via ansible. Where possible services are using both IPv6 and IPv4 IP addresses (some are even IPv6 only).
Public services
Teamspeak
A public teamspeak 3 server with plenty of space and bandwidth for voice chat.
Hostname: ts.schulze.xyz
In the past it was used for various groups and still boasts its original banner from -si.ka-
(waaaay back when we played the original counter strike, probably a good 10-15 years ago).
Downtimes/Maintenance:
Maintenance is “when teamspeak updates are released” and outside of peak times. The standard downtime for users is 2-5 seconds. If a downtime longer than a minute is expected, I post it in the “Message of the day” of the server a week in advance.
Internal services
Gameserver
I usually have one or more game servers running depending on what is currently of interest. Right now it is a “classic” cmangos server is online.
Proxy
Nothing too elaborate, just proxy servers located in Germany and USA with user authentication.
VPN
OpenVPN servers located in Germany and USA for tasks that require more than just a proxy or to access backend servers that aren’t using public IPs.
IRC Bouncer
Only reachable via IPv6 (although it can connect to IPv4 servers), only hosted in Germany.
Mailserver
Your usual mail server IMAP and Webmail. Supports email sub-addressing with “+” and “-” to help keep track of where an email was used.
Uses DKIM, SPF and DMARC as well as Spamassassin to keep Spam and misuse of the domains contained as well as possible.
Support for server-side sieve filtering and two MX servers (Germany and USA) so nothing gets lost in case of an unplanned downtime.
Wiki
This one is kinda in both categories, technically the wiki is publicly available, but large parts are walled off and only view able for logged in users.
I chose confluence as the software for this wiki since it is used by people with various degrees of technical knowledge and it has very affordable licences for small user bases.
Subversion
You can’t really maintain code without a version control tool. Subversion it is (mostly because the installation is > 10 years old).
Although I do have a gitlab in my test environment just waiting to see some action and eventually replace svn with git.
