Right now (08:34 PST) I can't get to IPv4 on wired network from room 1405.
IPv6 seems to be up, and the hotel wireless is up.

Brian -

The process for this week is for any in-room issues to initially be handled by the standard hotel tech support (which is provided by Roomlinx). If there's an infrastructure issue or something else beyond 1st level support, they will escalate to the IETF NOC via a local phone which rotates through VeriLAN staff.

I'll contact the local support. That unreachable message is coming from a router not on our subnet.

Both this ticket and #643 seem to be explained by a rogue DHCP server in someone's room, serving

And a response from RoomLinx?:

Edge -02 port 6 shows as "Above drop ceiling - Room 522"

This complicates things a touch. I'll reach out to AMS and see if we can determine who's in that room, if they are with IETF, etc...

Chelliot is going to be following up on this with AMS right now.

We believe the same device causing you issues was seen on the wireless subnet. We took it off the network and it has not reappeared. We have alerts set if it does.

I'm going to close this ticket. Please feel free to reopen it if the issue appears again.
