It looks like it is down on their website as well.

I really ought to look into building a custom tile server for it. Specifically, one for 2020 (the most current imagery) which is not in ELI since it is WMTS only.

@tsmock Thanks for the information! The issue was generated by our imagery test script (I should definitely change the user that creates these issues!) The script should close the issue automatically when it would detect that the imagery is online again. I'm not sure how likely this is given.

I did a quick search and found the following image server, that seems to host a WMS service for 2020 imagery: https://mcgis.mesacounty.us/image/rest/services/Mosaic_Datasets/City_County_2020/ImageServer https://mcgis.mesacounty.us/image/rest/services/Mosaic_Datasets

These ArcGIS server sometimes include a REST endpoint that can be used as WMS source. See https://github.com/osmlab/editor-layer-index/search?q=exportimage for examples.

It does have an exportimage parameter for WMS usage.

Example: https://mcgis.mesacounty.us/image/rest/services/Mosaic_Datasets/City_County_2020/ImageServer/exportImage?f=image&bbox=707158.8192363052%2C4321403.386123106%2C723414.8517483702%2C4329379.0020743385&imageSR=102206&bboxSR=102206&size=1920%2C942

While the server they use technically has that feature, it something I've been avoiding, since I don't know what additional resources are required for it. And since I'm not running the server, I've wanted to be careful in how badly their servers are hit.

And thus, I haven't made a PR for the 2020 imagery (see #734 ). I really need to look into setting up a mapproxy server.

@tsmock the linked service is also exposed as WMS:

....
{
    "properties": {
        "name": "City_County_2020",
        "type": "wms",
        "url": "https://mcgis.mesacounty.us/image/services/Mosaic_Datasets/City_County_2020/ImageServer/WMSServer?LAYERS=0&STYLES=default&FORMAT=image/jpeg&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap",
        "description": "2020 Air Photo. Eagleview project between city and county GIS",
        "available_projections": [
            "CRS:84",
            "EPSG:3742",
            "EPSG:4326"
        ],
...

But the server does not state any access constraints/license information. Thus, if there are not some other places with this information we should contact them anyway to ask for this information.
