API Performance Highlights

API Performance Highlights

For this week’s API performance highlights we’re going to talk about Barclays, some Fintech, and of course, the Department of Energy. Let’s get into it.

Barclays Personal in the Open Banking UK Production collection API performance
Barclays Business in the Open Banking UK Production collection API performance
Barclays in the Open Banking UK Open Data collection API performance

In order:

  • Barclays Personal in the Open Banking UK Production collection decreased by 13% from 8.11 (in the Green Zone) to 7.02 (in the Yellow Zone).
  • Barclays Business in the Open Banking UK Production collection decreased by 16% from 8.24 (in the Green Zone) to 6.91 (in the Yellow Zone).
  • Barclays in the Open Banking UK Open Data collection decreased by 13% from 7.3 (in the Yellow Zone) to 6.29 (in the Yellow Zone).

These were all due to a large spike in outliers on the 23rd and 24th of September, combined with a few DNS lookup failures.

This may have been an unplanned issue affecting a number of monitored endpoints and is logged as OBIE-11935 and OBIE-11936. They note that this may have been a result of a planned OBIE downtime. There was also a planned maintenance at the same time period which might be related OBIE-11896.

To us, this seems a bit of a long period of outages for planned maintenance. We wonder if it was used as an excuse for something that happened after maintenance? We’ll never know.

As an aside, we also cannot reach the Barclays developer portal either. Can you?

Stripe in the GGV Capital API-First collection API performance

Stripe in the GGV Capital API-First collection decreased by 11% from 9.41 (in the Green Zone) to 8.36 (in the Green Zone). This was due to a large increase in outliers affecting their one monitored endpoint from the morning of the 22nd of September.

Bank of Ireland in the Open Banking UK Open Data collection API performance

Bank of Ireland in the Open Banking UK Open Data collection was in the Red Zone with a CASC score of 4.5. 

And a hearty dongratulations to the Bank of Ireland this week. The major outage we reported last week has finally been fixed. It only took them four days to fix a production, client-facing API!

Top Drops in API Performance

ZB.com API performance

ZB.com in the Exchanges collection dropped 16 places. This was due to a number of very slow outliers around midday on the 23rd of the month.

Capital One in the Open Banking UK Production collection API performance

Capital One in the Open Banking UK Production collection dropped 12 places. This was due to a scattering of slow outliers throughout the week combined with a few HTTP 500 Internal Server Error failures on the 18th of September.

Hate-Watching the Department of  Energy’s API Performance

Dept of Energy in the US Government collection API performance

Dept of Energy in the US Government collection was in the Red Zone with a CASC score of 3.65.

Ahh, it’s you again, will you ever get out of our Red Zone? The Department of Energy has slightly improved this week with outlier rates coming down by 0.25% points to 16.5%.  So it’s slow but steady progress this week.
