Can a dev confirm if portal spawn rate was nerfed or not?

[Pandamoni]

I noticed tonight that I was seeing a lot fewer portals spawning and I asked a few people to see if it was a common theme amongst players. Everyone I asked has noticed a marked decrease in portal spawn rate. STG, if the rate was nerfed, will you please include it in the patch notes so we can decide if we want to spend our time doing something (farming) with such poor results? I wouldn't have spent an hour tonight portal hunting when I should be sleeping.
