Is github blocked in Iran ? or Its been censored by iran?

Dear Github
Access to many github servers have been blocked in Iran, these domains include:

raw.​githubusercontent.​com
github.community
and …
I have checked and I cant even ping the servers , my question is it github which is blocking the access? or it is Iran Censorship or is it a datacenter fault.
You can also check status of iran clients to these domain using below link

Thanks
