There have been some pretty bad issues with gmail recently. Some
changes have been deployed that will hopefully help mitigate those and
make things better, but it takes time to recover.

The massive backlogs caused by gmail have been enough to spill over
and affect other destinations as well simply due to the load created
since we have such a huge number of gmail subscribers. But we're
slowly seeing the backlogs shrink now and the load come down so
hopefully the changes made will continue to have effect and let us be
back to normal soon.
