EIP-4844 blob data has a limited protocol availability window; commitments persist but blob contents are not guaranteed to remain retrievable from normal nodes forever.
What to do next
Use a reputable archival service when you need historical raw blob data; do not confuse an archive gap with a reversed payment.
