Multiple reports have been coming in about Google’s Postmaster Tools data being missing for the past few days. Most reports indicate no data since 8/17, but some of my own domains were last updated on 8/16 even though they sent volume on the 17th.

Generally, GPT data runs a full 1-2 days behind, so the data for 8/17 was likely updated sometime the evening of 8/18. Even so, that leaves us on 3 days without updates. Not terribly uncommon, but many of us are still shook up after the 2-week-plus outage back in June. As usual, there’s been no official acknowledgement from Google.

GPT is a free tool, but it’s the only real insight (directly from Google) we as senders have into Google’s black box of mail filtering. I’m sure it’s not the highest priority project over there, but we sure do miss it when it’s not working properly.

UPDATE 8/22: Sometime last night EST Google appears to have populated data for 8/20 in my own instance and those of multiple others I’ve asked. Data is still missing for 8/18-8/19 (and 8/17 for a couple of my domains). Updates to the data generally happen for me late afternoon EST, so I’ll watch for any new data or backfilling later today.
