I have no problems with www1, it is my normal server and everything is working normally. I use www3 as my backup server, not noticed any issues either (but I don't monitor it).
Maybe you should move to a different server to see if things improve for you ?
Sorry, the fix two days ago has only been carried out on www1. www3 has been corrected today.
It might be necessary to click "Submit & Start" in "Personal Data" once to reset your PBX, if your account is on www3 and still malfunctioning in any ways.
