The terminal is mocking me. It\u2019s 03:14 AM. My eyes feel like someone rubbed them with a handful of fiberglass insulation. I\u2019ve been staring at this specific `Updating` state for forty-five minutes. In the world of azure, "Updating" is the polite way of saying "I\u2019ve fallen into a deep coma and I might never wake up." If you try to touch it, you get a 409 Conflict. If you leave it alone, your entire regional routing table stays in a state of quantum uncertainty.\n\nThe pager went off at midnight. "High Latency - US East 2." A classic. A masterpiece of understatement. It wasn't just latency; it was a total packet graveyard. The "architects"\u2014the guys who spend their days drawing pretty boxes in slide decks and using words like "synergy"\u2014decided last week that we needed to move to a "hub-and-spoke" model with a centralized NVA (Network Virtual Appliance). They promised it would simplify things. They lied.\n\n## The First Alert at 02:14: The Ghost in the VNet\n\nBy 2:00 AM, I realized the hub VNet was black-holing everything. I tried to check the effective routes on the primary gateway. The azure portal, that bloated, JavaScript-heavy labyrinth of broken dreams, just gave me a spinning blue circle. It\u2019s a special kind of hell when the UI designed to help you troubleshoot is the first thing to fail under load. \n\nI dropped back to the CLI. I needed to see what the hell happened to the User Defined Routes (UDRs).\n\n```json\n{\n  "addressPrefix": "0.0.0.0\/0",\n  "nextHopType": "VirtualAppliance",\n  "nextHopIpAddress": "10.0.0.4",\n  "provisioningState": "Succeeded",\n  "name": "DefaultRouteToFirewall"\n}\n<\/code><\/pre>\n
The JSON looked fine. On paper. But 10.0.0.4<\/code> wasn’t responding to ARP. The NVA was healthy according to the load balancer probes, but the traffic was just… vanishing. I started digging into the VNet peering. We have three spokes peering into the hub. One of them\u2014the most critical one, obviously\u2014was stuck in “Initiated” state. <\/p>\n
Why? Because someone (probably the same guy who thinks “serverless” means there are no servers) tried to enable “Use Remote Gateways” on a peering that already had a Gateway Load Balancer associated with the interface. You can\u2019t do that. The azure API won’t stop you from trying<\/em>, though. It\u2019ll just let the resource provider chew on that impossible request until it chokes and dies, leaving your VNet in the “Updating” state I\u2019m currently staring at.<\/p>\n
I tried to force a manual update.<\/p>\n
az network vnet update --ids \/subscriptions\/sub-id-here\/resourceGroups\/rg-core-connectivity\/providers\/Microsoft.Network\/virtualNetworks\/vnet-hub\n<\/code><\/pre>\n
Result? Another 500 Internal Server Error. The underlying Resource Manager is having a panic attack. I\u2019m on my fourth cup of sludge that used to be coffee. My keyboard is covered in crumbs from a protein bar that expired in 2022. <\/p>\n
