cm-vpn01 (mpt-vpn), cb-jumphost01, dm-wwwbuild01 (try server). 2
hours per host of downtime is affected.

Please let me know if you have any reason why we should not proceed
with the planned maintenance. As always, we aim to keep downtime to
as little as possible, but unexpected complications can arise causing
longer downtime periods than expected. All systems should be
operational by the end of the maintenance window. Feel free to email
infra at mozilla.com if you see issues past the planned downtime.

Thanks,
-Justin
