FEATURE REQUEST: don't stop updating the network if a domain is unreachable

Hello sirs. I wanted to know if some workaround or fix could be considered for this scenario: if you run a multisite network where every site has its own domain mapped to the network, when one of these domains is currently expired and unreachable, the entire network upgrade process is stopped with this error message:

cURL error 6: Couldn't resolve host 'expireddomain.com'

Can anybody involved in development consider this issue and add some code to workaround this and avoid this to stop entire networks from upgrading?
I’m currently facing one case where a network with 103 sites have failed with domains 3, 23, 68 and guess what… 96. You have to delete or archive the domain and rerun the upgrade process. It’s blatantly annoying 🙂

If you can simply add a button like “Roger that, now continue please” 🙂 it could be very handy and helpful.

And if you could also leave the domain marked as pending upgrade in My Sites screen, it could be even more helpful and nice.

Can anybody consider this feature request?
Thanks in advance!
