Summary of "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.
