Can't access any sites that begin with https://www.sites.google

[CSF1]

Hello everyone, 
Since we had a power cut other day I can no longer access sites.google.com or any other sites created by others via google.  I just get "this site can't be reached" message.

If I change my IP address using a VPN then I can access the sites, no problem, so I assumed this was a problem with the automatic IP address assigned to the Smarthub 2 after the power came back on. 

I have disconnected the hub several times to get a new public IP address but so far all IP addresses assigned to the hub do not provide access to sites.google.com. All IP addresses assigned appear to start with 109.15?.???.???

I have flushed the browse cashes and checked that this is an issue with all devices on the network, which it is!
I contacted the help Chat but all they wanted to do was reset the smarthub. 
Is there anything else I can do other to use my VPN whenever I want to access these sites?

Further to this: the top ping request is without the VPN and the second one is using the VPN, so why can't the host sites be found?

Thanks to whoever sorted this out at BTcoms - its now working again without having to use the VPN.
