Hello web,

my name is Chris Wolf, I am the new apprentice in Flying Circus.

I have start my training at the 01/08/2019 in the area of application development. My training at Flying Circus is very nice because the working atmosphere is very pleasant and you settle down fast. I am very interested in Computersoftware this is one of the reasons woe I want the Job by Flying Circus too.

I life in Halle since my birth until now and I am 16 years old now. Before I start my training at Flying Circus I was on the cooperative elementary school „Wilhelm von Humboldt“. I graduated from high school. 

Hello world!

I am Mohammad. I am 21 years old and the new trainee for computer scientist at Flying Circus.

I was born in Syria and came to Germany in 2015. It was a big step for me. Coming to a different country with a new language wasn’t always easy. But I think I did pretty well.  After my arrival I went to a German class. After that I decided to go to a High-School. There, I learnt most of my German.   

Since I was a child I always wanted to become a computer scientist for system integration. My dad deals a lot with computers at his job as  IT and I always helped him when I visited him.  My love for technology grew over the years. Every time one of my friends needs help with technology I am the person they go to and most of the time I find a solution.

So by now you probably noticed that working as a computer scientist has always been my dream and I am glad to be here. Hopefully, I can soon help you with your problems.

2018-08-30 – Umzug unseres Rechenzentrums-Labors / Moving our data center laboratory

Unser Büro ist letzte Woche wie geplant umgezogen und wir sind jetzt in der Leipziger Str. 70/71 beheimatet.

In der nächsten Woche werden wir unser Rechenzentrums-Labor ebenfalls aus der Forsterstraße in das neue Gebäude umziehen. Unser Labor besteht aus zwei Racks die unser produktives Rechenzentrum einmal zur Entwicklung und zur Qualitätssicherung detailliert nachbilden. Dort betreiben wir auch einige sekundäre Dienste (z.B. Build-Server, unseren Chat oder ein paar ausgewählte Monitoring-Skripte) durch deren Downtime der Produktiv-Betrieb nicht gestört wird.

Beim Umzug werden wir im Laufe des Donnerstags (30.08.2018) das Labor vollständig offline nehmen, umziehen und im Laufe des Nachmittags wieder in Betrieb nehmen.

Die Auswirkungen während der Umzugsphase werden voraussichtlich sein:

  • Deployments über unseren zentralen Build-Server (builds.flyingcircus.io) nicht möglich.
  • Konfigurationsänderungen von NixOS-VMs werden möglich sein, können jedoch beim Anfordern neuer Pakete mit erhöhtem Compiler-Aufwand verbunden sein.
  • Unser Support wird per E-Mail und Telefon aber nicht per Chat erreichbar sein.
  • Unser Support wird keinen Zugriff auf die zentrale Telemetrie haben und es werden für diesen Zeitraum auch keine zentralen Telemetrie-Daten erfasst.
  • Einzelne “Frühwarn-Checks” auf Infrastruktur-Ebene und die im Kundenportal definierten HTTP-Checks werden nicht verfügbar sein. Tests zur externen Verfügbarkeit der Anwendungen, sowie VM-spezifische Checks und die Statuspages werden wie gewohnt verfügbar sein.

Bei Fragen sind wir wie gewohnt über alle Kanäle ansprechbar.


 

Last week we moved into our new office building and are now located in the Leipziger Str. 70/71 in Halle (Saale).

Next week we’ll also move our data center laboratory to the new premises. The lab consists of two racks that fully model our productive data center environment for development and quality assurance. The lab also runs a couple of secondary services  (e.g. CI/CD servers, our chat, a couple of selected monitoring scripts, …) whose absence will not have an impact on the productive data center applications.

During the move on Thursday (2018-08-30) we’ll shut down the lab during the morning and rebuild and power everything up in the new location during the afternoon.

The projected impact of the secondary services during the move will be:

  • Deployments through our central build server (builds.flyingcircus.io) won’t be possible.
  • Configuration changes to NixOS VMs will be possible but may require substantial local package compilation.
  • Our support will be available by email and phone but not per chat.
  • Our support will not have access to central telemetry and our central telemetry will not record data for this period.
  • A couple of “canary checks” on the infrastructure level will be offline and HTTP checks defined through our customer portal will not be executed. External availability checks, regular VM checks and the status pages will be available as usual.

If you have any questions don’t hesitate to contact us through the usual channels.
