i do notice a bit more of latency, which translates to about +1% of CPU. I guess that in order to accurately report this you should have metrics for before and after the maintenance.
But looking quickly thru the API status: http://api-status.com/6404/117406/Google-App-Engine-API it seems like there's about 8% more latency than normal after Feb 7th On 9 February 2011 15:26, Stephen Johnson <[email protected]> wrote: > Update: > I pulled the reCaptcha jar out of the project just to make sure there wasn't > something funky in it and I redeployed.
