We believe we found the issue that is causing this node to be very slow: either due to an issue registering the node or due to s manual migration from the US region to the EU region, this node has its DB in the EU, but is still marked to execute in the US. This in turn makes the startup very slow, because of the sheet number of queries to start.

We will need to:

• [ ] Migrate the signer state to the watchtower in the EU
• [ ] Mark the node as a EU node so it starts colocated with it's DB

[cdecker]

We have identified a couple further nodes that are affected by this issue (<<1%) and are working on fixing up the migration logic to move the nodes to the right places.

[cdecker]

We have fixed up the migration script, allowing us to correct this issue. Now we iterate through the nodes and fix up all the discrepancies.

[cdecker]

All misplaced US nodes have now been migrated to the EU region. Now migrating the EU nodes to the US where necessary. This should be resolved by this evening.

[cdecker]

All misplaces EU nodes with DBs in the US have been moved to the US.
