Did an update hit you, or did your site go down?

Did an update hit you, or did your site go down?
This week on the radar — the boring infrastructure tools that prevent panic-misattribution.

🔗 [Uptime / status-code monitors] — flag the 5xx spell during a deploy that looks exactly like an algorithmic drop in your weekly data.
🔗 [GSC Crawl Stats — 'host status'] — Google's view of server availability during crawl; a soft 503 day tanks rankings, not an update.
🔗 [Update timeline trackers] — rule the algorithm in or out by date before you blame your content.

The tradeoff: rank tools tell you traffic fell; only availability monitoring tells you the cause was a CDN hiccup or a robots.txt that 503'd for six hours. Far more 'update' drops are self-inflicted outages than people admit.

One to bookmark: GSC host-status history — it timestamps the availability incidents your weekly rank report flattened into 'an update probably.'
