Hi noknojon
This issue seems to be resolved now.
The issue didn't affect malwarebytes updates, access to forum, etc; only access to the specific URL
www.malwarebytes.org. Other pages on the web site displayed OK. If you have been able to access that URL successfully, then most likely Telstra servers are not involved with your ISP, but we have yet to establish what caused it to happen, so it will probably be an ongoing puzzle.
