All dashboards down. All VPN's went down also

All of my dashboards are down but devices are accessible.  All of my IPSEC VPN's to my datacenter are down as well.

This appears to be an ISP internet issue at a large scale.

Just found out that both Level 3/Century Link are experiencing global outages.  Any data centers with Level 3 are down or bouncing.  Century Link is effecting all of their home internet users.  Marking this as solved, not a Cisco/Meraki problem directly

Uh, it is a Meraki issue if they are hosting in a L3 datacenter, and don't have appropriate alternate routes.

Does anyone have any useful updates on this outage?  We are an MSP provider, hundreds of customers affected by this outage.  What we have been able to determine is that if they are Meraki, they are down, if they are using Umbrella DNS, they are down.  A few we have been able to get into and change their DNS lookup servers to google dns has fixed (as least for the moment).  I got to Cisco's Umbrella status page, all green, no issues!? Not cool.

It's an ISP issue. Notinhg to do with Meraki. Apparently CenturyLink/Level3 related, AS3356.

Hello everyone,

 

Thank you for bringing this up.

 

I can confirm this is part of a wider internet outage and isn't Meraki specific.

 

You can see additional information on the outage here and here

 

Edit: Just to confirm, I do work for Meraki but it will take a few days for my account to be verified.

Kind of a big deal

This info from the CenturyLink master ticket on this issue was shared on the outages list about 90 minutes ago.  May be useful to give to execs, etc. asking what happened:

 

The IP NOC with the assistance of the Operations Engineering team confirmed a routing issue to be preventing BGP sessions from establishing correctly. A configuration adjustment was deployed at a high level, and sessions began to re-establish with stability. As the change propagates through the affected devices, service affecting alarms continue to clear.

 

Due to the nature of this outage, it may be necessary to reset your services locally at your equipment, or manually reset your BGP session. If after that action has been performed a service issue prevails, please contact the CenturyLink Repair Center for troubleshooting assistance.

What I find that is almost bizarre if not unprecedented, that since 2007 when I started using Meraki, I had never experienced a total dashboard outage that completely affected the operational integrity of a Meraki network until last week when there was an ISP issue in Europe that for about 2 hours we lost dashboards which also impacted on VPN access (I guess because the Meraki RADIUS db is hosted within the dashboard platform).

 

And then this has happened again today all be it in the USA

 

However, both outages caused by ISP's with BGP issues.

 

Ironically, one of the key features of BGP is to prevent this type of thing, I would hope (r) hope that some of the top network gurus in Meraki are re-assessing the peering and upstream connectivity and trying to understand why in one week there have been two ISP BGP issues that have taken down significant chunks of Dashboards.

 

I reiterate personally I have never seen this before in the history of Meraki - one would question if someone has made some changes recently to the network access and peering policies within Meraki (Cisco) that has exposed their network to a higher risk.
