         <p>A new version of <a href="https://github.com/SChernykh/p2pool/releases/tag/v3.1">P2Pool (v3.0+)</a> has been released with several improvements, which requires a consensus change.</p>
         <p>P2Pool (not Monero!) will hardfork to new consensus rules on <strong>March 18th, 2023 at 21:00 UTC</strong>. All versions before P2Pool v3.0 are incompatible. P2Pool v3.1 is recommended.</p>
         <p>If you keep using previous versions, you will keep mining as usual, but become almost a solo miner, as incompatible clients will mine on their own.</p>
+        <p>{% if getenv('NET_SERVICE_ADDRESS') == "p2pool.observer" %}After the fork, you can check on <a href="https://old.p2pool.observer/miner/{{ miner.address }}">OLD.P2Pool.Observer</a>.{% elseif getenv('NET_SERVICE_ADDRESS') == "mini.p2pool.observer" %}After the fork, you can check on <a href="https://old-mini.p2pool.observer/miner/{{ miner.address }}">OLD-MINI.P2Pool.Observer</a>.{% else %}Please check on an observer tracking the old chain.{% endif %}</p>
         <p>After upgrading to a supported P2Pool version and mine a share, this message will be dismissed.</p>
