In light of shrinking funding, we do need to look for a source to cover project expenses. If need be the OpenBSD Foundation can be involved in receiving donations to cover project electrical costs.
But the fact is right now, OpenBSD will shut down if we do not have the funding to keep the lights on.
If you or a company you know are able to assist us, it would be greatly appreciated, but right now we are looking at a significant funding shortfall for the upcoming year - Meaning the project won't be able to cover 20 thousand dollars in electrical expenses before being able to use money for other things. That sort of situation is not sustainable.
The OpenBSD project is the incubator for a number of other projects including OpenSSH and OpenSMTPD. If you use these or just want the project to survive, consider making a donation.
