Почему объявления приходят раньше, чем появляются на сайте объявлений.

Context

Investigation into why classified ads appear earlier in the internal reporting/monitoring system than they do on Avito (the external marketplace). The discussion is an internal status/debug report rather than a tutorial or review.

Systems / Components

• Internal “available/remote version” — the monitoring/availability view used by the team.
• Parser (scraper / indexer) — ingests ads from Avito into the internal system.
• Moderation pipeline — internal and/or Avito-side moderation that affects when ads become publicly visible.
• Test category — PlayStation hard drives (some games mentioned during checks).
• Test device — C8 mobile phone used for verification.

Observations

• The internal “remote” and “available” views sometimes display new ads before those ads are visible on Avito.
• The time offset is inconsistent:
  • Sometimes up to ~30 minutes.
  • Often 10–20 minutes.
  • Occasionally the internal view is only about a minute faster.
• The team believes the internal system’s earlier appearance is unlikely to mean the parser is “better.” More likely causes are timing/processing differences such as moderation and propagation delays rather than parser correctness.
• Parsers are currently unstable (described as “steering”/misbehaving), and this instability has been observed repeatedly.

Impact and Operational Notes

• The team experienced service problems and partial downtime totaling approximately 15 hours; an apology was issued and a short report will follow.
• Billing / invoicing: adjustments to rates/invoices for the affected three-day period were discussed.

Actions / Next Steps

• Further investigation and fixes are required to normalize timing and parser behavior.
• The team plans to coordinate and connect to resolve the discrepancies between internal views and Avito visibility.

Reviews / Guides / Tutorials

• None — the content is an internal debug/status discussion.

Main Speakers / Sources

• Internal product/technical team (reporting as “we”).
• Avito (external classifieds site being monitored).
