The ORBIT sandbox formerly known as sb2.orbit-lab.org was renamed sb6.cosmos-lab.org in the 2026 domain migration. Its documentation now lives at SB6 (two Q87T nodes with USRP X310s over 10 G, 60 dB coax interconnect, first sandbox with a data2 plane).
Not to be confused with sb2.cosmos — the COSMOS sandbox at Columbia University, NYC, which is a different facility.
