Hi All, Unfortunately it looks like this switch decided to reboot again last night at around 1AM PDT. Thankfully the impact was smaller than before with all of the adjustments we made in the recent weeks.
I wanted to send another update on how we're going to permanently fix this moving forward. I have racked two "new" Arista 1G switches which will replace two of the three Cisco Nexus fabric extenders where the majority of our hosts are. Once I have those plumbed into the new switches, I can start moving hosts over to these switches one by one. I'll send out another email with a list of hosts this will impact in a few weeks once it's ready. Before that happens we need to finish running fiber to our second core switch and finish the MLAG configuration and backend upstream connection. Once this is finished, we'll have more redundancy in our network. There will be another brief outage when we switch over to the new "core" switches with MLAG. Thanks again for your patience. Hopefully I can get these all done before this switch decides to reboot again!
