Most people seeing this are able to fix it by changing their DNS settings to Googles DNS setting @mdn_realdeal.
The Google Public DNS IP addresses (IPv4) are as follows:
- 8.8.8.8
- 8.8.4.4
The Google Public DNS IPv6 addresses are as follows:
- 2001:4860:4860::8888
- 2001:4860:4860::8844
Let me know if they make a difference.
