It should be possible to add a layer. I don't know ArcGIS, but you want
to add a TMS layer, and the URLs are something like

The layer is not a WMS layer, but a TMS layer. Data is consumed
minutely, but it uses a standard tile cache/tile store setup where it
stores previously rendered tiles and re-renders them when updated. Thus
there is no guarantee of currency. In general, it will behave the same
as the Standard layer on OpenStreetMap.org

I understand the server has been at 100% usage lately
