Recommendations to others considering Pantheon:
If you need hosting you can rely on for wordpress, choose another host. They do not take responsibility for their lack of planning. While they did give us a solution to THEIR hosting environment issues, it still had to be implemented by our in-house developers.
They touted that the site would be fast and spread across servers and reliable, we deployed a site and everything was fine. The trouble came when we started running ad traffic to the site. We hit between 150 and 200 concurrent visitors on the site and our website went down. At that point we reached out to their (Chat only) support and had to wait 50 minutes to get something changed. Once it was changed and the traffic died down the site came back up. Great. The solution from the chat agent was to upgrade our plan. So we went ahead and changed to the 'performance medium' and eventually the 'performance large' plan. Well that caused a whole other set of issues where the site went down again. What happened is that Pantheon could not properly serve all the resources to visitors of the site. So they sent us a link to github for some issue from 2018 that they said they knew about, but did not bother to let us know would affect our site until another 30 minute wait to get in contact with their chat support.
