msync.zoho.com having issues?

Nothing's changed on my end, but from about 8.31am EST today, my iPhone claims that the username or password is not correct when trying to check for mail. It is correct because I haven't changed anything and I am getting email on my computer's mail client and can log into webmail ok.

Are there authentication issues with the msync server currently?

Thanks
