What does 2105 (hist data farm disconnected) mean on the Interactive Brokers API?

Interactive Brokers lists TWS API warning message code 2105 with the text "A historical data farm is disconnected." (the vendor's wording). There is a connectivity problem to an IB server. Outside the nightly IB server reset, the vendor says this typically indicates an underlying ISP connectivity issue.

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
