GitHub Reports Two Incidents in June 2024 Affecting Service Performance

GitHub
has
released
its
June
2024
availability
report,
detailing
two
significant
incidents
that
resulted
in
degraded
performance
across
its
services,
according
to

The
GitHub
Blog.
These
incidents
affected
the
GitHub
Issues
and
GitHub
Migration
services,
causing
disruptions
and
delays
for
users.

Incident
on
June
5,
2024

The
first
incident
occurred
on
June
5,
2024,
starting
at
17:05
UTC
and
lasting
for
142
minutes.
During
this
period,
the
GitHub
Issues
service
experienced
degraded
performance.
Events
related
to
projects
were
not
displayed
on
issue
timelines,
which
include
actions
such
as
adding
or
removing
issues
from
projects
and
changing
their
status
within
a
project.

The
root
cause
was
identified
as
a
misconfiguration
due
to
a
scheduled
secret
rotation.
This
initiative
aimed
to
clean
up
and
simplify
service
configurations
for
improved
automation.
However,
a
bug
in
the
implementation
led
to
the
use
of
expired
secrets
by
one
of
the
configured
services,
resulting
in
the
performance
degradation.
GitHub
mitigated
the
issue
by
correcting
the
service
configuration
and
expects
that
the
simplified
setup
will
prevent
similar
incidents
in
the
future.

Incident
on
June
27,
2024

The
second
incident
took
place
on
June
27,
2024,
from
20:39
UTC
to
21:37
UTC,
lasting
58
minutes.
This
incident
affected
the
GitHub
Migration
service,
causing
all
in-progress
migrations
to
fail.
Upon
detecting
the
increased
failure
rate,
GitHub
paused
new
migrations
to
prevent
further
disruptions.
Although
this
led
to
longer
migration
times,
it
allowed
the
team
to
address
the
issue
without
additional
failures.

The
root
cause
was
traced
back
to
an
invalid
infrastructure
credential
that
required
manual
intervention.
Once
identified,
GitHub’s
first
responders
quickly
mitigated
the
issue,
resumed
the
paused
migrations,
and
restored
normal
service
levels.
To
prevent
similar
occurrences,
GitHub
is
enhancing
its
monitoring
and
alerting
mechanisms
for
infrastructure
credentials.

Future
Prevention
and
Monitoring

GitHub
has
committed
to
improving
its
monitoring
and
alerting
systems
to
prevent
such
incidents
in
the
future.
Users
are

recaps.
