History
On November 15, 1980, SBS 1 was launched by a Delta-3910 PAM-D from Cape Canaveral at 22:49 UTC.
In June 1990, SBS 1 was finally decommissioned and put into a graveyard orbit.[3]
gollark: No, that's silly, those would be handled by Java or something.
gollark: Maybe it's an issue with newer HTTPS certificate authorities?
gollark: <@201096871341588480> That's not the IP the requests are being sent from. I assume the quotas are actually being *tracked* somewhere, and *that quota is probably wrong* if you're getting the random bits via HTTP request from your proxy.
gollark: But *why*?
gollark: IPv6 is becoming increasingly important, what with all the issues with IPv4 address availability.
