I moved to Trustpower this month and when I got Static IP address some of the sites are not accessible, maybe their routing issue, cannot figure it out.

DNS resolving properly, but not getting a response, always timeouts.

initially, none of Microsoft Sites(office.com etc.) or Azure Datacenter hosted sites (even Trustpower.co.nz)

Anyone faced that and got fixed, appreciate your input since it will help me to go for it.
