We were affected by the downtime, suddenly our VPNs went down and we started troubleshooting if it was a switch sudden reboot, a physical problem, anything. Odd for some of our VPNs to randomly shut down rejecting all traffic but just at the endpoint. Then we started having some very specific problems with just some FTP addresses and couldn't figure out what was happening.

Until our CIO went to the bathroom and came back saying "Hey, these websites aren't working from our WIFI network but they're working fine from mobile data? Could it be a navigation problem from Orange?"

Then we realized it.
