Cannot access some web sites

Discovered this morning that some web sites cannot be reached. However, if I fire up my VPN all is fine.

I have rebooted my laptop and the Ignite modem, but no difference.Anyone experiencing this?

An example:

1. No VPN running

C:\>ping grc.com
Ping request could not find host grc.com. Please check the name and try again.

C:\>

 

2. With VPN active

C:\>ping grc.com

Pinging grc.com [4.79.142.200] with 32 bytes of data:

@Bplayer  Could this be related to recent issues brought up in this thread?  Ignite Parental Controls and Protected Browsing use DNS to restrict network access.  Using a VPN will bypass all of those protections.

 

Protected Browsing has also been known to cause strange connectivity problems sometimes, especially when it blocks access to non-malicious sites or blocks access to 3rd-party domains that a site relies on.  Do you have it enabled in the Ignite WiFi Hub?

 

If the Ignite Gateway is blocking sites even when Parental Controls and Protected Browsing are disabled, that's a bigger problem.

Parental Controls and Protected Browsing have always been disabled here.

It is strange as most sites are available, except for two. One is US and the other in UK:
grc.com

bbc.co.uk

Looks like the DNS is messed up.

Yup, but grc.com also fails to resolve using other servers, not just the Rogers DNS server:

 

$ nslookup
> server 8.8.8.8
Default server: 8.8.8.8
Address: 8.8.8.8#53
> grc.com
Server: 8.8.8.8
Address: 8.8.8.8#53

** server can't find grc.com: SERVFAIL
> server 9.9.9.9
Default server: 9.9.9.9
Address: 9.9.9.9#53
> grc.com
Server: 9.9.9.9
Address: 9.9.9.9#53

** server can't find grc.com: SERVFAIL
> server 1.1.1.1
Default server: 1.1.1.1
Address: 1.1.1.1#53
> grc.com
Server: 1.1.1.1
Address: 1.1.1.1#53

Non-authoritative answer:
Name: grc.com
Address: 4.79.142.200
> server 64.71.255.204
Default server: 64.71.255.204
Address: 64.71.255.204#53
> grc.com
Server: 64.71.255.204
Address: 64.71.255.204#53

** server can't find grc.com: SERVFAIL
