Network metadata+userdata and rate limits

We’ve been providing our VMs with metadata from the network for quite some time now and lately we’ve realized that when we reboot compute nodes for updates (so roughly 200 VMs are rebooting at once), some VM can’t access the metadata server. I believe this could be because of the nova-api ratelimiting, but I was unable to find proofs in the logs (No 403 forbidden at all in the log file). So, I was wondering :

-Can I disable the nova-api ratelimiting from paste-api.ini just as it was possible in kilo?
-Can I prevent cloud-init from running its latest user-data when it doesn’t receive metadata?

We currently use Pike on centos 7.
