UPDATE: as of april 7th, smurfy seems to be back up! ----- As you may be aware, Smurfy's mechlab since a few days gives a 503 error - service unavailable. I have not been informed with the details, but this influences a LOT of build on the forums. Sadly, this is something that is out of my control. As people in suggested in this thread it might be a temporary outage as they (finally) update the database, as a similar outage has been reported in 2018. We'll see when/if smurfy gets back up, and probably make some MechDB alternatives otherwise. We can use the webarchives of smurfy (courtesy of @Remover of Obstacles for posting these here) in the mean time Cheers, xCal
