siirtöillä

I’m unable to locate a widely recognized definition or usage of the term "siirtöillä" in Finnish. To ensure I produce an accurate, neutral wiki-style article, could you provide some context or clarify what this term refers to? For example:

- Is it a concept in linguistics, technology, geography, folklore, or another field?

- Is it a proper noun (a place, organization, or title) or a word form (such as a plural/adessive form of another word)?

- If you have a source or a brief definition, please share it.

Once I have the intended meaning, I will draft a concise, neutral article in plain text (under 300 words) without markdown formatting.
