The above is how I'm configuring my request to the SUPL library. I have seen almanac data from google's SUPL server maybe twice in the last 3 days. Is there something I'm missing in my request or is the google service just that unreliable for almanac?

The Google SUPL server missing Almanac data appears to be random. Sometimes its missing but most of the time it seems to be available. I still occasionally see it happening but it usually last for less than a day. No workarounds found.

Hello, did you ever get any answers why google stopped providing Almanac data? Any work around you've uncovered?

Hello John,

I think you would have to ask Google about this.

Another thing I should mention is that using that server in production might be a bit questionable licensing-wise, unless you already have an agreement with Google.
