Very strange thing happened, last Thursday, suddenly our office was having with portal.azure.com.
Today, we can't open any resources related to Azure. We can ping the azure URLs, but looking at wireshark trying to open a TCP connection - we get no ACK back.
The office internet is working 100% - diagnosed the network entirely - went as far as trying to connect on a edge network device outside of the FWs and still no dice.
This includes
df.onecloud.azure-test.net.trafficmanager.net
shed.dual-low.part-0014.t-0009.t-msedge.net
ppr-cdn-endpoint.azureedge.net
ppr-cdn-endpoint.afd.azureedge.net
azureedge-t-prod.trafficmanager.net
shed.dual-low.part-0014.t-0009.t-msedge.net
This isn't us trying to consume our own Azure setup - this goes for any and all devices in this specific office trying to hit anything hosted on azure (CDN, etc)
Tried opening up the sites on their IPs, everything.
As soon as we try to connect using a mobile hotspot instead of the LAN. Everything works.
Do Microsoft blacklist IPs perhaps? Anyone ever seen anything like this?

Check you Azure status below URL base on your region, also Twitter which is the official channel, last but not least, raise a ticket to Microsoft to work together to locate the issue would suggest:
https://azure.status.microsoft/en-us/status

@Kidd_Ip Hey thanks - how do we raise a ticket with Microsoft? We have raised it on our Azure portal but that ends up with needing paid 'technical' support for our Azure portal. Which this wouldn't be - this cannot be a 'setting' on our instance.
