Ok so my DNS changes have not made a difference. What has however made a difference is if I VPN to my office, which breaks out to the internet via SEACOM. My latency is higher, but at least I can connect... Would love to get this sorted out without that extra hop....
I have been experiencing this exact issue on VOX the last week or so. Also running on a 50mpbs FTTH. Im trying my DNS change now as i already have access to my router. Lets see how this goes....
