> in France. The lockdown in France started 17 March 2020 (week 12 of 2020).
> Traffic statistics for this week showed a 28% increase compared to the
> average of the previous 6 weeks. A comparative analysis was done between
> week 6 and week 12, and the following categories were compared:*

>    - *Queries for existing top-level domains (TLDs)*
>    - *Queries that originate from Chromium-based browsers*
>    - *Queries for large TLDs*
>    - *Queries for popular TLDs (.home, .lan, .corp, and .local)*
>    - *All other queries*
>
>
>
> *Most categories had an increase in traffic, contributing to the overall
> increase. The largest category of queries originated from Chromium
> browsers, which remained at about one third of all received requests. Some
> categories grew faster than others. The largest percentage increase came
> from the four categories of popular nonexistent TLDs (.corp, .home, .lan
> and .local). This is likely due to people working more from home, as
> normally workers are congregated in offices using a set of resolvers that
> understand how to respond to .corp, .lan, and .local domains. Now, they are
> now more dispersed and working from home using resolvers that may not
> understand how to respond to these domains. This would also explain the
> increase in .home queries: more people using the Internet more often from
> their homes.*

> *The effects of nationwide lockdowns have had a limited, but noticeable
> effect on the DNS traffic at IMRS instances when observed at a country
> level. This increase in DNS traffic can be observed overall and the fact
> that no issues have arisen suggests that the DNS architecture is well
> suited to scale during remote work and increased use at home.*

> Worth noting that the RIPE NCC Atlas probes were utilized to collect
