Sale is extened Till today just have a Look on interrail.eu or myinterrail.uk 

Due the High demand the Website crashed. They never had before so much Website visitors as in the last days. 

Thanks but I am concerned that if i have any problems when travelling the same might happen so I am reluctantly not buying

when traveling the Railcompany that caused the problem is responsible. so there is usually no need to reach out for eurails customer service. 

Unless the problem is with the pass 

I had till yet paperpasses and never had any struggles. 
I just bought a Mobile pass to try it out. (Usually i use a different offer instead of Interrail but the 50% discount worths to try it. )
