Yesterday everything worked fine. But tonight, I'm unable to access particularly a few particular websites on all the imacs, mbp and even iphones at home. Weirdly enough, a quick 4G access via my iphones show the sites are accessible, but when i get back on the home network (via wifi / ethernet), it becomes unavailable with these errors:
"This site can’t be reached.."
I've done all these tonight, but to no avail -- all on separate occasions on all imacs/mbp/iphone where possible:
cleared all cache, cookies and whatnots from google chrome..
updated osx to latest ElCapitan 10.11.6
restarted fibre modem, restarted router, restarted all computers/gadgets
tried sudo flushing my dns/mdns via terminal, but instead of receiving "say flushed" i got a "discoveryutil: command not found"
called the websites' web host techsupport and they're able to access the sites just fine.
& the best part about all this? Other websites work just fine. Only the few particular websites only. I'm bummed. Any pointers would be most grateful here.
IMHO, it's my router's DNS that's interrupting these few particular web addresses, but I am out of my wits to solve this. Heeeeeeelp~
