Understanding RSS Feed Polling Delays

Why Your RSS Feed Updates May Take Time

RSS feed automation checks feeds on a schedule. This explains why updates can take a few minutes, and sometimes longer.

How It Works

Think of it like checking your mailbox:

  • We check every 5 minutes

  • If we find mail, we check again soon

  • If we find nothing, we wait longer before checking again

  • After many empty checks, we wait up to 2 hours between checks

What This Means for You

When new items appear

  • Best case: 0 minutes (if we check right when a new item appears)

  • Typical case: 2–5 minutes (if a new item appears just after a check)

  • Worst case: up to 5 minutes (if a new item appears right after a check)

  • Rare worst case: up to 2 hours + 5 minutes (if your feed hasn’t had new items for a while)

Why delays vary

The delay depends on when a new item appears relative to our checks, and how long it’s been since we last found new items.

Example 1: Quick update (active feed)

  • 10:00 AM: We check your feed → no new items

  • 10:00 AM: You publish a new blog post

  • 10:05 AM: We check again → found it (5-minute delay)

Example 2: Very quick update

  • 10:00 AM: We check your feed → no new items

  • 10:01 AM: You publish a new blog post

  • 10:05 AM: We check again → found it (4-minute delay)

Example 4: Long delay (inactive feed)

  • Your feed hasn’t had new items for several days

  • We’ve been checking and finding nothing, so we wait longer between checks

  • 2:00 PM: Last check (no new items) → next check scheduled for 4:00 PM (2 hours later)

  • 2:30 PM: You publish a new blog post

  • 4:05 PM: We check again → found it (1 hour 35 minutes delay)

This happens because:

  • After finding no new items multiple times, we increase the wait time

  • Wait time increases: 2 minutes → 4 minutes → 6 minutes → 8 minutes → ... up to 2 hours maximum

  • Once we find new items again, we reset to checking more frequently

Why We Don't Check Every Second

  • Reduces server load

  • Reduces costs

  • Most feeds don't update every second

  • Prevents overwhelming feed servers

  • For inactive feeds, longer waits save resources

What You Can Expect

  • New items are usually detected within 2–5 minutes (for active feeds)

  • Sometimes it’s instant (lucky timing)

  • Sometimes it takes up to 5 minutes (normal)

  • For feeds that haven’t updated in a while, it can take up to 2 hours + 5 minutes

  • After we find new items, we resume checking more frequently

When Do Longer Delays Happen?

Longer delays (up to 2 hours) occur when:

  • Your feed hasn’t had new items for several days or weeks

  • We’ve checked multiple times and found nothing

  • The system increases wait time to save resources

Once we detect new items again, we reset to frequent checks (every 2–5 minutes).

Is This a Problem?

No. This is expected behavior. The system is designed to:

  • Check regularly without overloading servers

  • Find new items quickly on active feeds

  • Be efficient and reliable

  • Save resources on inactive feeds
