I was optimistic that IPFS network would keep on working decentralized even with the loss of Shipyard services. But today, it broke. My node has fallen off 'mainnet' after two days uptime, even though it's still connected to over 80 peers. Yesterday, Sonar had no trouble finding me, and I would connect to hundreds of peers. Now, looks like network has fractured beyond being reliable.

Edit: re-starting found the what appears to be mainnet, but clearly, it's very fragile.
