Dear Cloudflare Customer:

Thursday afternoon=2C we published a blog post describing a memory leak ca=
used by a serious bug that impacted Cloudflare's systems. If you haven't y=
et=2C I encourage you to read that post on the bug:

https://blog.cloudflare.com/incident-report-on-memory-leak-caused-by-cloud=
flare-parser-bug/

While we resolved the bug within hours of it being reported to us=2C there=
 was an ongoing risk that some of our customers' sensitive information cou=
ld still be available through third party caches=2C such as the Google sea=
rch cache.

Over the last week=2C we've worked with these caches to discover what cust=
omers may have had sensitive information exposed and ensure that the cache=
s are purged. We waited to disclose the bug publicly until after these cac=
hes could be cleared in order to mitigate the ability of malicious individ=
uals to exploit any exposed data.

In our review of these third party caches=2C we discovered data that had b=
een exposed from approximately 150 of Cloudflare's customers across our Fr=
ee=2C Pro=2C Business=2C and Enterprise plans. We have reached out to thes=
e customers directly to provide them with a copy of the data that was expo=
sed=2C help them understand its impact=2C and help them mitigate that impa=
ct.

Fortunately=2C your domain is not one of the domains where we have discove=
red exposed data in any third party caches. The bug has been patched so it=
 is no longer leaking data. However=2C we continue to work with these cach=
es to review their records and help them purge any exposed data we find. I=
f we discover any data leaked about your domains during this search=2C we=
 will reach out to you directly and provide you full details of what we ha=
ve found.

To date=2C we have yet to find any instance of the bug being exploited=2C=
 but we recommend if you are concerned that you invalidate and reissue any=
 persistent secrets=2C such as long lived session identifiers=2C tokens or=
 keys. Due to the nature of the bug=2C customer SSL keys were not exposed=
 and do not need to be rotated.

Again=2C if we discover new information that impacts you=2C we will reach=
 out to you directly. In the meantime=2C if you have any questions or conc=
erns=2C please don=E2=80=99t hesitate to reach out.

re Customer:<br>
<br>
Thursday afternoon=2C we published a blog post describing a memory leak ca=
used by a serious bug that impacted Cloudflare's systems. If you haven't y=
et=2C I encourage you to read that post on the bug:<br>
<br>
<a href=3D"http://cloudflare.us5.list-manage.com/track/click?u=3Dd80d4d742=
66c0c044b0bcd7ca&id=3D3ff7537b84&e=3Dd339a9adda" target=3D"_blank" style=
=3D"mso-line-height-rule: exactly;-ms-text-size-adjust: 100%;-webkit-text-=
size-adjust: 100%;color: #2BAADF;font-weight: normal;text-decoration: unde=
rline;">https://blog.cloudflare.com/incident-report-on-memory-leak-caused-=
by-cloudflare-parser-bug/</a><br>
<br>
While we resolved the bug within hours of it being reported to us=2C there=
 was an ongoing risk that some of our customers' sensitive information cou=
ld still be available through third party caches=2C such as the Google sea=
rch cache.<br>
<br>
Over the last week=2C we've worked with these caches to discover what cust=
omers may have had sensitive information exposed and ensure that the cache=
s are purged. We waited to disclose the bug publicly until after these cac=
hes could be cleared in order to mitigate the ability of malicious individ=
uals to exploit any exposed data.<br>
<br>
In our review of these third party caches=2C we discovered data that had b=
een exposed from approximately 150 of Cloudflare's customers across our Fr=
ee=2C Pro=2C Business=2C and Enterprise plans. We have reached out to thes=
e customers directly to provide them with a copy of the data that was expo=
sed=2C help them understand its impact=2C and help them mitigate that impa=
ct.<br>
<br>
Fortunately=2C your domain is not one of the domains where we have discove=
red exposed data in any third party caches. The bug has been patched so it=
 is no longer leaking data. However=2C we continue to work with these cach=
es to review their records and help them purge any exposed data we find. I=
f we discover any data leaked about your domains during this search=2C we=
 will reach out to you directly and provide you full details of what we ha=
ve found.<br>
<br>
To date=2C we have yet to find any instance of the bug being exploited=2C=
 but we recommend if you are concerned that you invalidate and reissue any=
 persistent secrets=2C such as long lived session identifiers=2C tokens or=
 keys. Due to the nature of the bug=2C customer SSL keys were not exposed=
 and do not need to be rotated.<br>
<br>
Again=2C if we discover new information that impacts you=2C we will reach=
 out to you directly. In the meantime=2C if you have any questions or conc=
erns=2C please don=E2=80=99t hesitate to reach out.<br>
