Hello, over the past couple of weeks, we’ve noticed a huge and unusual spike in traffic on our HubSpot site. Normally, our daily page views are in the range of 500–1,000 per day, but suddenly this jumped to nearly 13,000 per day.

Looking at the analytics, the majority of this traffic is coming from China (over 59k sessions in the last 30 days), which is not typical for us since we rarely had traffic from that region before. The targeted pages were our tutors listing page and some tutor profile pages (all populated from HubDB). We are getting similar results on our Google Analystics.

We have since unpublished those pages, but the traffic has now shifted to the 404 error page. It’s worth noting that the tutors pages were always set with noindex headers, so they shouldn’t have been appearing in search results.

We already have bot filtering enabled in HubSpot and all relevant settings turned on, but clearly this isn’t catching everything. On other subdomains (hosted outside of HubSpot).

At this point, we’re looking for advice on:

• Better bot filtering in HubSpot – is there anything beyond the built-in options?

• Country-level blocking or filtering (especially for China, in this case).

• Integrations or workarounds that might allow something like Cloudflare protections on HubSpot-hosted content.

Has anyone dealt with a similar spike, especially with traffic concentrated in one unexpected country?

Thanks in advance!
