# RSS feed returns 410 Gone, parser errors

## TL;DR
A 410 Gone on an RSS feed means the publisher deliberately retired that feed URL, and unlike a 404 it will never come back. Do not retry it; remove the URL from the poll list and find the feed's replacement, usually announced on the publisher's site or discoverable via their current RSS autodiscovery tags. Treat 410 as a permanent redirect to a new source, not a transient failure.

## The error
```text
HTTP 410 Gone
(feed URL retired; parser received an error page instead of XML)
```

## When this helps
- an RSS feed starts returning 410 Gone
- a news pipeline loses a publisher source
- auditing feed health across the poll list
- replacing retired feeds

## When it doesn't
- the error is 404; that may be temporary, retry before replacing
- the feed content moved but the URL redirects; follow the redirect instead
- you need historical entries; a new feed only carries new items

## Works with
Any HTTP client and feedparser for python. 410 semantics are HTTP standard.

## Steps
### 1. Confirm the 410 and stop polling the URL
```bash
curl -s -o feed.html -w "HTTP %{http_code}\n" -A "IntelBriefingBot/1.0" "https://YOUR-publisher/old-feed.xml"
grep -il "gone\|retired" feed.html | head -2
```
Expected: HTTP 410 confirmation. A 404 might be temporary; a 410 is the publisher saying the feed is gone for good.

### 2. Look for the replacement feed via autodiscovery
```bash
curl -s -A "IntelBriefingBot/1.0" "https://YOUR-publisher/" -o home.html
grep -o "https\?://[^ \"]*rss[^ \"]*\|https\?://[^ \"]*feed[^ \"]*\|https\?://[^ \"]*\.xml" home.html | sort -u | head -10
```
Expected: Candidate feed URLs from the homepage's autodiscovery tags. Publishers that retire feeds usually publish the replacement the same way.

### 3. Validate the replacement feed parses
```python
import feedparser
d = feedparser.parse("https://YOUR-publisher/new-feed.xml")
print("entries:", len(d.entries))
print("feed title:", d.feed.get("title"))
print("bozo (parse error flag):", d.bozo)
```
Expected: A parsed feed with entries and no bozo flag. Only swap the URL after the replacement proves healthy.

### 4. Swap the URL in the poll list and note the retirement
```python
import json
polls = json.load(open("feeds.json"))
polls["https://YOUR-publisher/new-feed.xml"] = polls.pop("https://YOUR-publisher/old-feed.xml")
json.dump(polls, open("feeds.json", "w"), indent=2)
print("feed URL swapped; old URL retired")
```
Expected: An updated poll list. The agent never wastes another request on the retired URL.

## Other ways people phrase this
### rss feed 410 gone error
Permanent retirement. Replace the URL; do not retry.

### feed parser error gone feed
The parser fails because the body is an error page. Fix the URL, not the parser.

### rss feed retired replacement
Autodiscovery tags on the homepage are the standard way to find the replacement.

## Why it happens
Publishers retire feeds during redesigns and CMS migrations, and 410 is the correct status for a deliberately removed resource. Feed readers that treat 410 like a transient error poll a dead URL forever. The content continues under a new URL; the 410 is the signal to go find it.

## Edge cases
- Some publishers return 410 for feeds that moved to a new domain; check the publisher's announcements.
- Archived entries from the old feed stay valid; keep them and append new entries from the replacement.
- A 410 on every feed of a publisher can mean the publisher dropped RSS entirely; switch to their API.
- Validate the replacement for a full poll cycle before deleting the old URL from config.
