Hey y'all,

So I'm on 2Degrees Fibre and for a little over 2 weeks now I have identified a frustrating problem with accessing Facebook when I'm assigned certain IPv4 IP addresses on 2Degrees.  The issue is that images are not loading in Chrome web browsers or even the iOS Facebook and Instagram apps on my mobile devices.  When trying to access via Chrome I can see it stalling out 5-edge-chat.facebook.com in the Chrome status bar. Using Chrome Inspector there are massive amount of pending request tied to Facebooks CDN network (fbcdn.net).

Here's the kicker...

This *only* occurs if I have been issued an IPv4 address in the following ranges (that I have identified so far...there could be more)

151.210.149.0/24

151.210.150.0/24

151.210.153.0/24

I can instantly resolve this issue on my mobile devices, laptop, or desktop system by connecting to a VPN or by bouncing my 2D PPPOE session until I get issued an IP address outside of those subnets (e.g. 111.69.182.0/24).

I have reported this to 2D 11 days ago and they can only tell me 'they are investigating'.  My guess is this is probably confusing the heck out of lots of other poor 2D customers who land on those subnets.

So, I'm just kind of making this post as a PSA (Public Service Announcement) in case anyone else is vexxed by this problem. 

If for some reason someone is on one of those subnets and Facebook is working for you, I'd be fascinated to hear about it, though.  This problem is totally device/platform agnostic for me. 

And before anyone else posts this question....Yes, I have checked IP Tables at the firewall level and, no, I don't have any weird rules that would affect just those network ranges
