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.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">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.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Thanks again for your patience.
