Classic Any active guild doing ironman challenges in Europe?

I want to try the ironman challenge (rules = https://ift.tt/2NFSLjd) but I don't think my server is the ideal to do so. Is there any server in EU that has some other people doing challenges? I feel it would be a lot funnier if we could share experiences.Thank you very much! via /r/wow https://ift.tt/3akZney
